Non Ending Tape Problems :-(

[Hubert Palme]

Hello,

after upgrading the kernel to 2.0.33 (The former 2.0.29 suddenly begun
again with process hangups :-(), I have a new tape problem: After some
(long) time of writing, tar is cancelled with I/O Error. I tried
another tape, but the same problem. Short tars's were
successfull. This is the log:

Feb 15 14:58:45 palme-pc kernel: scsi0: Referenced SCB 255 not valid during SELTO. 
Feb 15 14:58:45 palme-pc kernel:         SCSISEQ = 0x5a SEQADDR = 0x4 SSTAT0 = 0x15 SSTAT1 = 0x8a 
Feb 15 14:59:05 palme-pc kernel: scsi : aborting command due to timeout : pid 138981, scsi0, channel 0, id 1, lun 0 Read (10) 00 00 39 f9 34 00 00 02 00  
Feb 15 14:59:06 palme-pc kernel: SCSI host 0 abort (pid 138981) timed out - resetting 
Feb 15 14:59:06 palme-pc kernel: SCSI bus is being reset for host 0 channel 0. 

And the second trial:
