just to re-confirm, my problem with termination is nothing to do with linux.
it also crashed windows boxes as well. The problem was that the Sony tape
drive was not providing good/correct termination, and in turn was causing
the scsi bux to reset.
Your problem does sound similiar.
The basic rule to follow is:
Termination at the ends of the cable and no were else.
