31acd246c0 Allow the specification of the controller bus when wiring down scsi buses.
This is performed by using a line similar to:

controller scbus0 at ahc0 bus 1

to wire scbus0 to the second bus on an adaptec 2742T controller.

ffc2aaf2d8 Do not set SCSI_NOSLEEP on every tape command (the exception being during
probes).  Apart from there being no reason to set SCSI_NOSLEEP on every
tape command, this prevents controller drivers from sleeping when resources
are fully utilized causing unecessary "Oops not queued" errors.  This is
only noticed for controllers that can run out of resources like the
27/2842 adaptec controllers.  Before this fix, it is almost impossible to
perform extended tape operations if more than one scsi disk is on the
bus with the tape drive with these controllers.  This does not address a
similar problem that could occur if devices are probed while other targets
are active since SCSI_NOSLEEP will still be set in that case.

>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

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.

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?
