freebsd-4.11-p3 bacula-1.36 onstream ADR50 SCSI External tape drive well I just dont know what all this means so I am asking for some guidance. I was backing up to an onstream ADR50 tape drive with bacula. The process since errored and the daemon is stopped. I dont know why these Infinite interrupt loop messages are ending up every minute in the /var/log/messages file. clues please? --- snip --- Jun 5 21:48:27 typhoon /kernel: Infinite interrupt loop,
