second LUN to show up.
mjacob's change (which is correct) in rev 1.21 of cam_periph.c to elminiate
infinite retries of the SCSI busy status bit seems to have broken probing
of Pioneer changers that aren't already quirked.
The right way to fix this is probably to change things around so we can
guarantee 100% sequential probing of LUN-based changers even if they aren't
quirked. This should fix things for now, though.
The same goes for CD drivers and tape drivers. In systems with mixed IDE
and SCSI, devices in the same priority class will be sorted in attach
order.
Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of
drivers have been modified to use that priority.
This includes the necessary changes to all drivers, except the ATA drivers.
Soren will modify those separately.
This does not include and does not require any change in the devstat
version number, since no known userland applications use the priority
enumerations.

fail on some units.
If we've already unloaded the tape, don't try and rewind and
unload in saclose. This is a slightly riskier change because
we're now going to depend on SA_FLAG_TAPE_MOUNTED to say whether
we've really unloaded the tape. This involved changing the
setting in sadone for tape errors to SA_FLAG_TAPE_FROZEN (which
is more accurate anyway-if you get an EIO you've probably lost
tape position anyway) where it used to just clear the mounted
flag.
