Did you see my posting on almost the same day reporting
problems with the same controller as you have and
a CD-ROM drive? I can get the machine to boot, but
when I mount from the CD I see the exact same error
messages as you do. From our mutual problems, I suspect
the problem is with the controller, not the SCSI
devices attached. The controller is rather new.

I don't have the ability to submit a problem report
using send-pr right now - do you? Have you submitted
a report yet? Did you get any response?

I am copying this reply to the freebsd-hackers list
in hope that someone there might already be working on
the problem, or be interested enough to read the
two articles in the newsgroup before they expire.

   Hi,

   my new machine has an Adaptech 2940 Ultra SCSI host adapter with
   an IBM DORS SCSI2 (2 GB) disk, a CD ROM and a DAT drive attached to
   it. Now, when I write to the DAT, everything seems O.K., however,
   when trying to read, I sometimes get:

   ahc0: target 6, lun 0 (st0) timed out
   st0(ahc0:6:0): BUS DEVICE RESET message queued
   and then:
   st0(ahc0:6:0): Target Busy

   I can't figure out, what is wrong here, since sometimes reading works
   just fine.
