AIC 7892 problem
Hello All,
I have some messages in /var/log/syslog & /var/log/messages when i did a backup into tape drive as below:

These message appear time to time. I've tried to google for this problem, but haven't figured anything, beside that: FYI
I'm running kernel 2.4.20-xfs, whith integrated AIC 7892 scsi controller.
