5dc76893af wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>

This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.

In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
   Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
   until they finish.  The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
   This prevents the user from locking the tape driver by strange
   tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
   is displayed at the WCHAN column of the `ps' command as:

	wtread    reading data from the tape
	wtwrite   writing data to the tape
	wtrfm     reading the tape marker
	wtwfm     writing the tape marker
	wtrew     rewinding the tape
	wterase   doing WTQICMD ERASE operation
	wtretens  doing WTQICMD RETENS operation
	wtorew    doing MTIOCTOP REW/OFFL operation
	wtorfm    doing MTIOCTOP FSF operation
	wtowfm    doing MTIOCTOP WEOF operation

7) It's possible to use the tape with "default density",
   useful for devices which don't support density switching
   or do automatic format determination.
8) Some controllers support only 1024 block length.
   Setting WT_BSIZE bit in device minor number turns on this mode.

Minor number structure:
	0bfffuuu
Fields:
	uuu   - Unit number. It's possible to install
		up to three tape controllers on the same machine,
		using DRQs 1..3.  Hence, unit number can lie
		in range 0..2.
	fff   - Tape format number:
		0 - /dev/rwt0  - default density (auto select)
		1 - /dev/rwt0a - QIC 11 (obsolete)
		2 - /dev/rwt0b - QIC 24 (60 megabytes)
		3 - /dev/rwt0c - QIC 120 (120 megabytes)
		4 - /dev/rwt0d - QIC 150 (150 megabytes)
		5 - /dev/rwt0e - QIC 300 (300 megabytes?)
		6 - /dev/rwt0f - QIC 600 (600 megabytes?)
	b     - Long block size flag.  With this bit set,
		the driver will perform all i/o operations
		with the controller using 1024-byte
		blocks, instead of 512 ones.
		Some controllers need it (CMS for example).
		If you Wangtek controller does not stream well,
		you can try to use /dev/rWt0 device instead
		of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
		to create it).

Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly.  Use raw interface instead.

Thanks to all who helped to test it on the following hardware:

57e834d0b1 1) Added proc file system from Paul Kranenburg with changes from
John Dyson to make it reliably work under FreeBSD.
2) Added and enabled PROCFS in the GENERICxx and LINT kernels.
3) New execve() from me. Still work to be done here, but this version
	works well and is needed before other changes can be made. For
	a description of the design behind this, see freebsd-arch or
	ask me.
4) Rewrote stack fault code; made user stack VM grow as needed rather
	than all up front; improves performance a little and reduces
	process memory requirements.
5) Incorporated fix from Gene Stark to fault/wire a user page table
	page to fix a problem in copyout. This is a temporary fix and
	is not appropriate for pageable page tables. For a description
	of the problem, see Gene's post to the freebsd-hackers mailing
	list.
6) Tighten up vm_page struct to reduce memory requirements for it. ifdef
	pager page lock code as it's not being used currently.
7) Introduced new element to vmspace struct - vm_minsaddr; initial
	(minimum) stack address. Compliment to vm_maxsaddr.
8) Added a panic if the allocation for process u-pages fails.
9) Improve performance and accuracy of kernel profiling by putting in
	a little inline assembly instead of spl().
10) Made serial console with sio driver work. Still has problems with
	serial input, but is almost useable.
11) Added -Bstatic to SYSTEM_LD in Makefile.i386 so that kernels will
	build properly with the new ld.

2c48c35e86 From: Jeffrey Hsu <hsu@soda.berkeley.edu>
The following patch adds the addr argument to signal handlers.

The kernel with the patch is no more and no less in compliance or in
violation of POSIX and ANSI C than the kernel before the patch.

The added functionality this addr argument provides is quite useful.  It
enables an entire class of algorithms which use mprotect to trace memory
references.  Beside garbage collectors, I have heard of this technique being
applied to debuggers and profilers.  The only benchmarking I've performed is
using akcl to compile maxima:  without the kernel patch, it takes 7 hours to
compile maxima, while with stratified garbage collection, it only takes 50
minutes.

Basically, I can't think of a reason not to add the addr argument and there
is a compelling need for it.

If you find the patch acceptable, please let me know so I can send my
FreeBSD akcl config files to wfs for inclusion in the core akcl release.
The old 386BSD config files there won't work on either NetBSD or FreeBSD.

db1888bf05 Reset fdc during probe.
From: <dec@lazarus.nrtc.northrop.com>
   Changes between EPSILON and RELEASE of FreeBSD have again caused
the kernel to not see my floppy disk drives.  I don't know what happened,
'cause I don't see any changes to fd.c, but here is an old fix that
I have applied to the probe routine which will solve the problem (at
least for me).  Since this is a rather brute-force solution - I understand
if you want to ignore it...

1b23af429b Patch from Gene Stark:
Subject: Page fault in PTE area fails in copyout
Index: sys/i386/i386/trap.c FreeBSD-1.0.2

Description:
	Reading files of several megabytes into Emacs, or many small
	files all at once, would fail with "IO error - bad address".

Repeat-By:
	The bug can be exercised by a test program that malloc()'s
	a 5MB chunk of memory, and then, without accessing the memory
	first, filling it with data from a file using read().
	(I read 64k chunks from /dev/wd0d into successive 64k regions
	of the 5MB chunk.)  The read() will fail with EFAULT at the first
	virtual address boundary that is a multiple of 0x400000.

Fix:
	The problem was code in sys/i386/i386/trap.c that tries to
	figure out what kind of trap occurred and to handle it appropriately.
	It was interpreting any page fault with virtual address
	>= vm->vm_maxsaddr as being a user stack segment fault.
	In fact, addresses >= USRSTACK are in the user structure/PTE area,
	and if they are handled as stack faults, the proper PTE will
	not be paged in when it is supposed to be.  This situation comes
	up in copyout() and copyoutstr(), if PTE's are accessed for the
	first time ever.  The page fault on accessing the nonexistent PTE
	is mishandled as a stack fault, and then the fault that occurs on
	the subsequent access to the page itself causes copyout to fail
	with EFAULT.

Subject: IDE-disk hangs - solution/patches NetBSD/FreeBSD
Summary: fixes for lost interrupts with IDE disks
Keywords: hanging-disk, IDE-disk, lost-interrupt


Due to "popular" demand I'm posting these patches to NetBSD/FreeBSD
instead of mailing them around the world :-)

As many have found out there is a problem when using IDE disks on
FreeBSD. Following is a patch that fixes the problem with lost intterrupts.
Both fixes is based on a patch posted here some month ago by
Stefan Behrens?? (sorry I've lost the original article). But anyway it
works (for me :-).
Basically it does a timeout on lost interrupts, starting the operation
again and logging and error message on the console.

It additionally makes the allready present while loop timeouts
independent of CPU speed, and adds minor numbers for easy access to
dos partitions.

aa3ae6ef2a First steps in rewriting locore.s, and making info useful
when the machine panics.

i386/i386/locore.s:
1) got rid of most .set directives that were being used like
	#define's, and replaced them with appropriate #define's in
	the appropriate header files (accessed via genassym).
2) added comments to header inclusions and global definitions,
	and global variables
3) replaced some hardcoded constants with cpp defines (such as
	PDESIZE and others)
4) aligned all comments to the same column to make them easier to
	read
5) moved macro definitions for ENTRY, ALIGN, NOP, etc. to
	/sys/i386/include/asmacros.h
6) added #ifdef BDE_DEBUGGER around all of Bruce's debugger code
7) added new global '_KERNend' to store last location+1 of kernel
8) cleaned up zeroing of bss so that only bss is zeroed
9) fix zeroing of page tables so that it really does zero them all
	- not just if they follow the bss.
10) rewrote page table initialization code so that 1) works correctly
	and 2) write protects the kernel text by default
11) properly initialize the kernel page directory, upages, p0stack PT,
	and page tables. The previous scheme was more than a bit
	screwy.
12) change allocation of virtual area of IO hole so that it is
	fixed at KERNBASE + 0xa0000. The previous scheme put it
	right after the kernel page tables and then later expected
	it to be at KERNBASE +0xa0000
13) change multiple bogus settings of user read/write of various
	areas of kernel VM - including the IO hole; we should never
	be accessing the IO hole in user mode through the kernel
	page tables
14) split kernel support routines such as bcopy, bzero, copyin,
	copyout, etc. into a seperate file 'support.s'
15) split swtch and related routines into a seperate 'swtch.s'
16) split routines related to traps, syscalls, and interrupts
	into a seperate file 'exception.s'
17) remove some unused global variables from locore that got
	inserted by Garrett when he pulled them out of some .h
	files.

i386/isa/icu.s:
1) clean up global variable declarations
2) move in declaration of astpending and netisr

i386/i386/pmap.c:
1) fix calculation of virtual_avail. It previously was calculated
	to be right in the middle of the kernel page tables - not
	a good place to start allocating kernel VM.
2) properly allocate kernel page dir/tables etc out of kernel map
	- previously only took out 2 pages.

i386/i386/machdep.c:
1) modify boot() to print a warning that the system will reboot in
	PANIC_REBOOT_WAIT_TIME amount of seconds, and let the user
	abort with a key on the console. The machine will wait for
	ever if a key is typed before the reboot. The default is

	panic message rather than just a number. Lot's of work to

98dbbc5399 genassym.c:
Remove NKMEMCLUSTERS, it is no longer define or used.

locores.s:
	Fix comment on PTDpde and APTDpde to be pde instead of pte
	Add new equation for calculating location of Sysmap
	Remove Bill's old #ifdef garbage for counting up memory,
	that stuff will never be made to work and was just cluttering
	up the file.

	Add code that places the PTD, page table pages, and kernel
	stack below the 640k ISA hole if there is room for it, otherwise
	put this stuff all at 1MB.  This fixes the 28K bogusity in
	the boot blocks, that can now go away!

	Fix the caclulation of where first is to be dependent on
	NKPDE so that we can skip over the above mentioned areas.
	The 28K thing is now 44K in size due to the increase in
	kernel virtual memory space, but since we no longer have
	to worry about that this is no big deal.

	Use if NNPX > 0 instead of ifdef NPX for floating point code.

machdep.c
	Change the calculation of for the buffer cache to be
	20% of all memory above 2MB and add back the upper limit
	of 2/5's of the VM_KMEM_SIZE so that we do not eat ALL
	of the kernel memory space on large memory machines, note
	that this will not even come into effect unless you have
	more than 32MB.  The current buffer cache limit is 6.7MB
	due to this caclulation.

	It seems that we where erroniously allocating bufpages pages
	for buffer_map.  buffer_map is UNUSED in this implementation
	of the buffer cache, but since the map is referenced in
	several if statements a quick fix was to simply allocate
	1 vm page (but no real memory) to it.

pmap.h
	Remove rcsid, don't want them in the kernel files!

	Removed some cruft inside an #ifdef DEBUGx that caused
	compiler errors if you where compiling this for debug.

	Use the #defines for PD_SHIFT and PG_SHIFT in place of
	constants.

trap.c:
	Remove patch kit header and rcsid, fix $Id$.
	Now include "npx.h" and use NNPX for controlling the
	floating point code.

	Remove a now completly invalid check for a maximum virtual
	address, the virtual address now ends at 0xFFFFFFFF so
	there is no more MAX!!  (Thanks David, I completly missed
	that one!)

vm_machdep.c
	Remove patch kit header and rcsid, fix $Id$.
	Now include "npx.h" and use NNPX for controlling the
	floating point code.

	Replace several 0xFE00000 constants with KERNBASE

Document that KERNBASE should really be KPTDPTDI << PDRSHIFT, for
now leave it as the constant 0xFE000000 until I make a seperate
common header file for this stuff (vmaddresses.h?)

Remove NKMEMCLUSTERS define, it was only being used to define
VM_KMEM_SIZE, so why have all the indirection.  Besides who wants
to work in CLBYTE sizes chuncks.


pmap.h:

Fix $Id$ and some other minor format clean ups.

Remove the XXX comment about NKPDE, since it now has the correct value
of 7.

Remove unused LASTPTDI and move the APTD into the very end of memory to
free up 4MB of kernel virtual address space.
Remove unused RSVDPTDI and free up 12MB of kernel virtual address space.


vmparam.h

Fix $Id$.

Increase SHMMAXPGS to 512 (2MB) now that there is room for it to be
bigger.  The XXX comment stays until the kernel moves down in memory
to free up enough space to use the proper default of 4MB.

VM_KMEM_SIZE is now a direct constant stating the size of the kernel
malloc region.  Increased the value from 3MB to 16MB.

line of Makefile.i386.  Fixes the extra rule that gmake complains about
for machdep.o.  This fix is from Joans 0lsson.

Rework the depends and rules for assym.s and genassym so that we now use
the .depend rule for genassym.o such that if you change any header files
that are included by genassym.c the right things happen.  This is probably
what has caused more bad kernel builds than any other thing in the
Makefile.i386!

2b976dc12a ALL:
Removed patch kit headers and rcsid strings, add $Id$.

isa.c:

Removed old #ifdef notyet isa_configure code, since it will never be
used, and I have done 90% of what it attempted to.

Add conflict checking code that searchs back through the devtab's looking
for any device that has already been found that may conflict with what
we are about to probe.  Checks are mode for I/O address, memory address,
IRQ, and DRQ.  This should stop the screwing up of any device that has
alread been found by other device probes.
Print out messages when we are not going to probe a device due to
a conflict so the user knows WHY something was not found.  For example:

aha0 not probed due to irq conflict with ahb0 at 11

Now print out a message when a device is not found so the user knows
that it was probed for, but could not be found.  For example:

ed1 not found at 0x320

For devices that have I/O address < 0x100 say that they are on the
motherboard, not on isa!  The 0x100 magic number is per ISA spec.  It
may seem funny that pc0 and sc0 report as being on the motherboard, but
this is due to the fact that the I/O address used is that of the keyboard
controller which IS on the motherboard.  We really need to split the
keyboard probe from the display probe.  It is completly legal to build
a pc with out one or the other, or even with out both!

npx.c:

Return -1 from the probe routine if we are using the Emulator so
that the i/o addresses are not printed, this is the same trick used
for 486's.

Do not print the ``Errors reported via Exception 16'', and
``Errors reported via IRQ 13'' messages any more, since these just lead
to more user confusion that anything.  It still prints the message
``Error reporting broken, using 387 emulator'' so that the person is
aware that there mother board is ill.

Eliminate constant PDRPDROFF, now use PDTDTPI to control location of PTD,
PTDmap and PTDpde

Eliminate constant APDRPDROFF, now use APTDPTDI to control location of APTD,
APTDmap and APTDpde.

Still need to fix Sysmap location (it is still a constant).

.globl statements are now consistent with respect to <comma><space>, the
<space> being removed from all .globl statements.

Document the fillkpt macro as to what registers control what.

Fix some comments that went past column 80, and clean/line some others up.

Remove constand for _Crtat, now use KERNBASE+constant, this still needs work.

Replace constants for offsets of sigcode parameters with symbolic names
from assym.s

Mark the sigreturn() call with XXX since we use the hardcoded constant
for the system call number, this is bogus and should be a #define or
something some place!

The kernel before and after this change was verified with cmp, not one
byte changed.  These are all cosmetic clean up changes that makes the
code more correct and easier to move the kernels virtual address space
and size.

Okay, I tracked down the d*mn thing that is causing the memcpy to be
emmitted by gcc2.  In the following patch is a fix to eliminate the
one place that was causing gcc to do the memcpy in function ie_readframe
for the ie_recv_frame_desc rfd = *(ie->rframes[num]) structure copy.

I also fixed the code so that the NS (XNS) support would compile with
out error and removed the cruft #define ns_* stuff from the softc
structures (I did this a while back for all the other either drivers)

Removed the $Log$ and all of the old log stuff, that is all kept in
the cvs tree, no need to duplicate it in the file... I'll copy it
into my commit message so that it is all retained, except the
revision numbers are going to get screwed up.

It now compiles cleanly under my LINT kernel...

$Log$ stuff from Garretts original file
 * $Log$
 * Revision 1.32  1993/06/20  15:56:15  wollman
 * Fixed warning message.
 *
 * Revision 1.31  93/06/20  15:52:28  wollman
 * More compilation lint.
 *
 * Revision 1.30  93/06/20  15:48:16  wollman
 * Commented all the rest of the cast-qual warnings.  Might be
 * fixed someday by changing the prototypes of bcopy(), bzero(), etc.
 *
 * Revision 1.29  93/06/20  15:40:13  wollman
 * Started fixing some of the cast-qual warnings (most just commented).
 *
 * Revision 1.28  93/06/12  20:39:14  wollman
 * Changed definition of MK_24 to silence -Wcast-qual.
 *
 * Revision 1.27  93/06/08  17:05:57  wollman
 * Attach routine now returns void.
 *
 * Revision 1.26  93/06/08  16:31:21  wollman
 * Deleted attempt to set watchdog timer, since we don't use it.
 *
 * Revision 1.25  93/04/16  22:15:31  wollman
 * Fixed infinite loop in iestart() which would cause the transmitter
 * to constantly step on the Ethernet, sending the same two packets over
 * and over again.  This crashes the router (really!) and makes other
 * network users very angry.
 *
 * Revision 1.24  93/04/14  23:57:47  wollman
 * Increased transmit buffer size from 1504 to 1512, just in case I don't
 * understand how the MTU is used.
 *
 * Revision 1.23  93/04/14  23:16:19  wollman
 * Fix iestart() so that it only tries to execute a command if one was
 * queued up (oops...).
 *
 * Revision 1.22  93/04/14  23:02:16  wollman
 * Unknown changes.
 *
 * Revision 1.21  93/04/12  18:29:33  wollman
 * Added multiple transmit commands.  Note that they are always queued in
 * pairs (there are only two to begin with), and the I flag is only set
 * on the second one.  This should decrease interrupt activity somewhat.
 *
 * Revision 1.20  93/04/12  15:36:05  wollman
 * Changed setup of config block to take into account difference between
 * StarLAN (10BASE-T) and Ethernet: StarLAN is Manchester, Ethernet is NRZ.
 *
 * Revision 1.19  93/03/23  18:58:44  wollman
 * Raised count of receive buffers from 32 to 48 and included analysis of
 * memory usage in a comment near that definition.
 *
 * Revision 1.18  93/03/18  03:59:53  wollman
 * Last try to get large TCP windows to work...
 *
 * Revision 1.17  93/03/18  03:54:10  wollman
 * Added RNR processing as a part of receive interrupts.  Hopefully this
 * will make everything Just Work now.
 *
 * Revision 1.16  93/03/18  03:23:24  wollman
 * Still having problems with RNR conditions.  Basic problem: say we
 * set TCP window to 16k, which is a semsible value.  Then smart
 * partners will blast 16k to us, of which we can fit 8k minus a bit
 * into our buffers.  (Need to look at that memory map..)  So, we get
 * an RNR interrupt.  The problem is, what do we need to do in this case?
 * The original code doesn't work, but it doesn't hang the system either.
 *
 * Revision 1.15  93/03/18  02:37:00  wollman
 * Disabled watchdog timer.  This gets called from a timeout somewhere,
 * which is running up at softclock.  This is at a higher priority than
 * we are, so we can get interrupted in the process of receiving something
 * by the timer expiration, which is not a nice thing to have happen.
 * Question: how can we keep this functionality, but do it in sync with
 * our interrupts?  (Ugh!)
 *
 * Revision 1.14  93/03/18  02:35:46  wollman
 * Fixed some more problems with receive code---it works!
 *
 * Revision 1.13  93/03/17  20:15:59  wollman
 * Think we fixed the serious (showstopper) bugs in 1.12.
 *
 * Revision 1.12  93/03/15  17:45:39  wollman
 * Changed filtering logic dramatically to avoid the unnecessary copyin
 * for BPF or multicast routing when the packet is not for us.  (We
 * have to run in promiscuous mode in this case.)  We still need to
 * deal with the problem of allocating one mbuf per receive buffer;
 * we should be able to get away with a single mbuf for all reasonable
 * incoming packets, and using an mbuf cluster will help avoid unnecessary
 * copying of data.
 *
 * Revision 1.11  93/01/30  20:23:15  wollman
 * Fiddled with reset code to hopefully make it work better when the
 * watchdog timer expires.  Question: why does it make a difference that
 * we do the same thing through ieioctl() as we were doing before.  The
 * old code, when iereset() was called, the receive unit would completely
 * die.  But, a cycle of ifconfig ie0 down ; ifconfig ie0 up' would bring
 * things back to normal.  So, we try to mimic that now.  Grrr...
 *
 * Revision 1.10  93/01/29  17:26:50  wollman
 * Finally fixed multicast routing/BPF mb_map full problem!!!!
 * It turned out that, when we received a packet not for us, we
 * would just return from ie_readframe(), *WITHOUT* freeing the
 * mbuf that the packet was in.  So, when running in promiscuous
 * mode (i.e., multicast routing or BPF without -p), we would have
 * (on our extremely busy subnet 4) a memory leak of epic proportions.
 *
 * We now hold on to a single mbuf chain allocated in this way,
 * and the next time a packet is read, we free it.  Also, the
 * next time a packet is transmitted, we free it.  This way,
 * we never lose more than 6 mbufs total (and on average more like
 * 3).
 *
 * Revision 1.9  93/01/23  14:22:21  wollman
 * Added some StarLAN Fiber modifications from L. Jonas Olsson.
 *
 * Revision 1.8  93/01/23  14:02:34  wollman
 * Added support for IP multicasting.
 *
 * Revision 1.7  92/11/21  17:51:59  wollman
 * Added StarLAN Fiber version point to my driver.
 *
 * Revision 1.6  92/11/20  18:21:45  wollman
 * Fixed documentation, made out-of-mbuf condition an error.
 *
 * Revision 1.5  92/11/20  18:14:02  wollman
 * Move change of ethertype to host byte order so that it's after
 * bpf_mtap.  Hopefully, this will allow us to listen to incoming
 * IP packets.
 *
 * Revision 1.4  92/11/20  18:11:00  wollman
 * Added code to drop packets when we run out of mbufs rather than
 * panicking.  This should alleviate the problems observed when using tcpdump.
 *
 * Revision 1.3  92/11/14  14:12:40  wollman
 * Added BPF support code.
 *
 * Revision 1.2  92/11/14  13:30:26  wollman
 * Added RCS keywords

a27ff697e2 This is a fix for the 32K DMA buffer region that was not accounted for,

basically, reserve a new 32k space right after firstaddr,
and put the buffer space there...

the diffs are below, and are in ~cgd/sys/i386/i386 (in machdep.c)
on freefall.  i obviously can't test them, so if some of you would
look the diffs over and try them out...

Description:
	Old wt driver is too incomplete and buggy.
	It does not support Archive controllers, BSD-like
	tape ioctls, multiple tape controllers, different
	tape density etc.
Fix:
	This driver is a replacement of the old one.
	It was not tested on different controllers, though.

	This is the streamer tape driver for 386bsd and FreeBSD,
	which supports Wangtek and Archive controllers.
	It was developed as a replacement of the old Wangtek
	tape driver from CMU.

In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
   Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
   until they finish.  The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
   This prevents the user from locking the tape driver by strange
   tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
   is displayed at the WCHAN column of the `ps' command as:

	wtread    reading data from the tape
	wtwrite   writing data to the tape
	wtrfm     reading the tape marker
	wtwfm     writing the tape marker
	wtrew     rewinding the tape
	wterase   doing WTQICMD ERASE operation
	wtretens  doing WTQICMD RETENS operation
	wtorew    doing MTIOCTOP REW/OFFL operation
	wtorfm    doing MTIOCTOP FSF operation
	wtowfm    doing MTIOCTOP WEOF operation

Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly.  Use raw interface instead.

To bring this error try to make two swap partitons on one disk:
one of the partitions will be not recognized.
Fix is simple: set uninitialized val variable.

The only place I found with a printf("status %x") is in /sys/i386/isa/lpt.c,
and looks much like a left-over debugging printout...

And it was... I changed it to an lprintf (which is defined if debuggin is on)
