Probably this does not apply to you or it won't solve your problems (because your SCSI controller is different than mine) but I was getting SCSI timeouts with 2.0.30 and an Adaptec AHA-2940U with two hard disks and one DAT tape unit. I was unable to make it work but all the problem went away when I upgraded to 2.0.32. It was just like that: magic. Why don't you try going to 2.0.32? It culd happen to you as well...
Good luck, E.- P.S. The timeouts only ocurred while trying to backup to tape. During normal disk operation (no tape activity) everything was just fine. William D.
