Oops on 2.4.13-pre6 (sparc64)

Ah, Mondays.

The following oops happened after approximately eleven days of uptime.
The machine was not under any particular load at the time.  Following
a forced reboot, all filesystems replayed the journal successfully.

Relevant log entries leading up to the oops:

  Nov  4 04:54:08 localhost kernel: attempt to access beyond end of device
  Nov  4 04:54:08 localhost kernel: 03:02: rw=1, want=401891121, limit=102312
  Nov  4 04:54:08 localhost kernel: Assertion failure in __journal_remove_journal_head() at journal.c:1634: "buffer_jbd(bh)"

The filesystem in question is the root filesystem.  The taint was
caused by the openprom module, which was the only module loaded.

Please let me know if you need any further data.


ksymoops 2.4.3 on sparc64 2.4.13-pre6.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.13-pre6/ (default)
     -m /boot/System.map-2.4.13-pre6 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to
map, modules, ksyms etc.  ksymoops -h explains the options.
