Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Run Bacula btape program 2.Enter the "fill" command 3. Actual Results: The program reports its progress periodically as follows: ...

Now beginning re-read of tape ... 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. Additional info: 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 IDE-SCSI drive.
