I'd make sure that your SCSI bus is correctly terminated, etc.  However,
there are some known (?) bugs IIRC with timeout handling in the wd33c93
SCSI driver.  Unfortunately, I forgot all the little SCSI clue I once had,
so I don't even have good diags for you to try.  Does `hinv' from the PROM
report the drive OK, or does IRIX see it if you have an IRIX installation?
