This was fixed recently in -current. If you have kernel source, the
patch is simple. I've appended it to this message.

It was actually a SCSI system bug that hit the 2742 particuallarly hard
because of the way it allocates per command resources.

Try the patch and get back to me. As the author of the driver and the
proud new owner of a tape drive, you should see rapid progress on these
problems.

Already being done. Between the aic7xxx driver and the SCSI system as a
whole, all of my free time is already allocated.
