>Synopsis:       Booting w/scsi tape in drive causes first use to fail

Booting with a tape in a SCSI tape drive will cause the first
use of the tape to fail with the following message:

st0: bad request, must be between 0 and 0.

d9bf888a1b sdsize() didn't open a device often enough. This caused swap partitions on
slices other than the first slice looked at to be unavailable for swapping.

3586bcab62 Finally implement the kernel hook for the "mt eom" command. (The
user-level part has already been commited.)

Note that i've lost the "official" code for this; it went into the
system after 1.1.5.1.  The commited code is my own version, but it has
proven to work for me for more than a year now.

a34bad999b Set SCSI_NOSLEEP only when we really need to. This requires an additional
flags parameter to all xxstart routines so that the correct information can
be passed down into the device specific routines.  This is needed to ensure
that ccb/scb allocation routines don't hang.

a1c6084710 Support disk slices. This involves mainly replacing inline code with
function calls.  Broken tracking of open partitions gets fixed as a side
effect.  Races in sdopen() and sdioctl() become more numerous than before.

Close the device in sdsize().  Media removal could not have worked right
when unused swap devices were held open.  There may now be a problem
with used swap devices not being held open.

Fix ancient operator precedence bug in sddump().  It may have been
possible to attempt dumping to unloaded media.

Remove NetBSD ifdefs.  We're too different now, and the NetBSD driver was
already too different for them to be relevant.

Remove support for soft write protection.  There are no ioctls to set it,
and this driver never set it either.  It was used in the wd driver to
disable writing to unlabelled disk, but we want to support writing to
foreign partitions on unlabeled disks.

Clean up some formatting and restore some old-style function headers.

Fix it so that calls to extend_get won't dereference 0 when "swap
on sd.." calls sdsize() on systems with no SCSI devices.

This probably really fixes Poul's "boot with no SCSI" problem.

2f8f2dd5bb >From a week or two ago I got kernel panics as soon as I tried to access my
tape drive. I traced it to sys/scsi/scsi_base.c where some code were added
to print the return values of the sense command. My tape drive returned a
extended flags value of 0x20, so the key that is the lower 4 bits, is 0.
The code uses "key-1" to index into a table and then the kernel go to never-
never land.

Here is a fix for this. Will somebody please apply it?
