This looks like either a bug in the scsi driver, or else an undiscovered
bug that's pulling a buffer out from under the driver. The patches
you're using have fixes for all the known problems of the latter
possibility, so we really should track this one down.

Could you check whether you have all the latest fixes for your scsi
driver, and whether there are any outstanding bug reports of this sort
for the driver?
