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. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.5 (X11; Linux i686; U;) Gecko/20020606 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 is made. 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: ... Simple test (single tape) selected. btape: Wrote label to prelabeled Volume on device /dev/nst0 btape: btape.c:1121 Wrote block=5000, VolBytes=322,495,678 rate=820.6 KB/s ... btape: btape.c:1126 Flush block, write EOF btape: Error in block.c:229 block.c:228 Expected block-id BB01 or BB02, got ´O½).

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 ...
