Jun 16 18:39:18 chuck /kernel: (sa0:ahc0:0:3:0): tape is now frozen- use an OFFL
INE, REWIND or MTEOM command to clear this state.
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...
Thanks in advance,
Peter
