Hi Justin,

I'm having a little problem with my AHA-2940.  I can no longer use my
Exbyte 8505 8mm drive to back up my SCSI hard drive.  Using a 2.2-STABLE
kernel in single user mode from 4/24 I got:


DUMP: 91.33% done, finished in 0:03
st0(ahc0:4:0): SCB 0x2 - timeed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0
SEQADDR == 0x8
st0(ahc0:4:0): Queueing an Abort SCB
st0(ahc0:4:0): Abort Mesasge sent
st0(ahc0:4:0): SCB 2 - Abort Completed
st0(ahc0:4:0): no longer in timeout
DUMP: End of tape detected
sd0(ahc0:0:0): SCB 0x1 - timed out in message out phase, SCSISIGI == 0x0
SEQADDR == 0x0
sd0(ahc0:0:0): SCB 1: Yucky Immediate reset. Flags = 0x1
sd0(ahc0:0:0): no longer in timeout
sd0(ahc0:0:0): Issued Channel A Bus Reset.  3 SCBs aborted.


And then the machine froze (not even a panic).  Note, that Dump shouldn't
have detected EOT as I was dumping a 2gig partition on a tape that should
hold 5gig minium.  I've used this tape to backup the SCSI drive before,
even while multiuser.  So I think it has something to do with an aic7xxx
change.  Maybe?
