    Um, well as you might already know, the 5000/200 doesn't have an asc! So
I don't understand how it could time out! I would try removing the Tape
drive and see if you still run into the same problem. You're using the
4.4BSD driver right (rzX disks), and not the 53C9x driver (sdX)? Something
very fishy is going on. It's possible that the tape drive is leaving the
SCSI bus in a strange state, or your chain is just unhappy. Either way it's
pretty weird. You might want to send-pr it so Jason Thorpe or someone who
knows more about the driver could help you.
