Yesterday I had time to try the backup with the aic7xxx again. It crashed again! My disk is ID#0, TAPE is #1 First I had three messages in syslog (manual copy): 21:00:38 scsi: aborting command due to timeout: pid 48677, scsi0, channel 0, id 0, lun 0 Read(6) 0f f0 2c 04 00 21:00:42 scsi: aborting command due to timeout: pid 48678, scsi0, channel 0, id 0, lun 0 Wrute (6) 0c 08 80 08 00 21:00:44 scsi: aborting command due to timeout: pid 48679, scsi0, channel 0, id 0, lun 0 Read(6) 0c 08 88 04 00 And on the console I had (kernel dubug flag set, klogd -c8 after fix) SCSI : aborting command due to timeout: pid 48677, scsi 0, channel 0, id 0, lun 0 Read (6) 0f f0 2c 04 00 SCSI host 0 abort (pid48677) timed out - resetting SCSI bus is being reset for host 0 channel 0.
