Description of problem:
Writing 64K fixed size tape blocks to a Seagate Model: STT20000A
tape drive using the ide-scsi driver causes a kernel
panic when the end of tape is reached and a rewind request
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Run Bacula btape program
2.Enter the "fill" command
Actual Results: The program reports its progress periodically as follows:
Simple test (single tape) selected.

The kernel panics and rebooting is necessary.
Expected Results: As above, except that the tape should rewind and
the program should read back what it wrote.
At the point of the system crash, the program is using
system read(), write() requests and a few simple ioctl() requests
(e.g. rewind). There is absolutely nothing fancy, no
special modes ...
If the system stays up, dmesg should be captured.
Otherwise, a serial console or netdump must be established.
Also, the release field is obviously wrong in the report (4.2).
I need to see /etc/redhat_release and /proc/versions.
Unfortunately, I no longer have access to the system that has the
