Subject2.0.36pre10 oops

Some good news first: 2.0.35 locked hard consistantly while doing a
backup, 2.0.36pre10 is the first 2.0.36 I've tried and I only got an Oops,
rather than a hard lockup with it. Much improved! :)

Relevant info: AMD 486-133, BusLogic BT-932, running a backup with BRU
from a Quantum SCSI drive to an HP DAt.
