I have a Spectralogic dual AIT tape library attached to a dual Pentium
II that I am trying to run under 2.2.3. The tape library works fine
under 2.0.36. Since a departmental backup solution is the last thing
keeping us from wide deployment of Linux in our department, I'd like
to see if I can get any advice. I believe the problem lies with the
generic scsi driver, since the tape library has a robot arm which
needs to be commanded though the scsi passthough driver.

Both 2.0.36 and 2.2.3 detect the dual tape drives at st0 and st1, and
detect the robot arm as sgi. (The system having six scsi drives
attached).

The error message when a problem occurs are:
