RE: SCSI bus reset when burning



I have this same type of problem when I try to use SCSI tape backup.
I get simular error messages and the machine's load goes pretty high and
sometimes needs to be rebooted.

I have had no luck getting the tape backup to work.

this is the error i get:
--
May  3 14:23:23 taz kernel: SCSI host 0 abort (pid 228089503) timed out -
resetting
May  3 14:23:23 taz kernel: SCSI bus is being reset for host 0 channel 0.

We both have Adaptech controllers.......
