I thought it was bad tapes, so I replaced them. Same result. So I replaced the tape drive, cable and SCSI card. Still no joy. It's an Adaptec 2940 and a Travan 5 SCSI 10/20 gig drive. This same set up has worked for 3 years without problem. It finally occurred to me (just a few minutes ago), that 3 weeks ago, is about the time I upgraded from 4.7-STABLE to 4.8-STABLE. Is it possible that the ahc driver is broken? Any help on this would be greatly appreciated...
