<snip report of 'random' SCSI DAT errors>

FWIW, Yes I have a very similar situation.  A number of identical
machines with ASUS P2B-DS motherboards, using on-board adaptec, Kernel
2.0.37, AIC7xxx 5.1.19/3.2.4, Seagate Ultra Disks and Sony DAT's.

Some machines seem good as gold and others come up with seemingly random
SCSI timeouts when writing to the DAT.

This does seem to be a recurring problem for a number of people - what
can we do to track the cause down?

FWIW, an error extract and my /proc/scsi follows:-

(scsi0:0:6:0) Synchronous at 10.0 Mbyte/sec, offset 15.
scsi : aborting command due to timeout : pid 31420641, scsi0, channel 0, id 0, lun 0 Read (10) 00 00 4a fd 66 00 00 02 00 
SCSI host 0 abort (pid 31420641) timed out - resetting
SCSI bus is being reset for host 0 channel 0.
(scsi0:0:4:0) Synchronous at 5.0 Mbyte/sec, offset 15.
(scsi0:0:0:0) Synchronous at 40.0 Mbyte/sec, offset 15.
(scsi0:0:1:0) Synchronous at 40.0 Mbyte/sec, offset 15.
st0: Error with sense data: extra data not valid Current error st09:00: sense key Unit Attention
Additional sense indicates Power on, reset, or bus device reset occurred
