I do not think this is a hardware problem. The same backup done
with pre2.0.6 had no problems using the same tape. This problem
also occurred with the pre2.0.7 kernel.

After this last message is logged, the shell from which the tar command
was issued, and tar drive are locked up and unusable. All other SCSI
devices are accessible and respend to commands.
Guess I will stick with pre2.0.6 to do my tape backups.
