   I have several servers with AHA2940UW's on them that I have been using 
   since the day 2.1-R was out.  They haven't yet given me a problem, what 
   possible things should I be on the lookout for, just in case, and will 
   they be fixed in 2.1.5-R?  I don't like using -snap, -stable, or -current 
   on production boxes.

I submitted the problem as report kern/1296. What you might see
is this:
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

(where st0 could be some other scsi device like cd0)

followed by the machine hanging so only a reset will get you out.
The evaluator of the PR sent me this comment:

I haven't had a chance to do this - the machine is not heavily
used and I've been too busy.
