Bug 66663

Description of Problem:

Got the following error from EXT3 using the 2.4.18-4 kernel on a dual
CPU box with 4 disks (arranged as a software RAID mirrored pairs).

The machine in question was still accepting input at the command line, however
shutdown command failed (because of broken filesystem?) and required
powercycle. No errors reported by fsck -f on any filesystem.

Version-Release number of selected component (if applicable):

kernel-smp-2.4.18-4

How Reproducible:

Not very I'm afraid. We have three identical machines all running Redhat 7.3
for a number of weeks without any problems. The machine in question has been
fine since it was rebooted on Monday. Just thought that I ought to report
a potential problem with EXT3.

I found the following on the ext3 developers list. Its the same assertion
failure but a different kernel version: I don't know if this is relevant.
