When doing a backup to my DLT occasionally, I get the following:

(sa0:ahc0:0:2:0): SCB 0xc - timed out while idle, LASTPHASE == 0x1, SEQADDR == 0xa
(sa0:ahc0:0:2:0): Queuing a BDR SCB
(sa0:ahc0:0:2:0): Bus Device Reset Message Sent
(sa0:ahc0:0:2:0): no longer in timeout, status = 34b
ahc0: Bus Device Reset on A:2. 1 SCBs aborted
(sa0:ahc0:0:2:0): LOAD UNLOAD. CDB: 1b 0 0 0 1 0 
(sa0:ahc0:0:2:0): UNIT ATTENTION asc:28,0
(sa0:ahc0:0:2:0): Not ready to ready change, medium may have changed


Am I hitting the end of the tape, or something else?


Here's my config:

ahc0: <Adaptec 2940A Ultra SCSI adapter> rev 0x01 int a irq 9 on pci0.9.0
ahc0: aic7860 Single Channel A, SCSI Id=7, 3/255 SCBs
ahc1: <Adaptec 2940 Pro Ultra SCSI adapter> rev 0x01 int a irq 10 on pci0.10.0
ahc1: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs
