Steps to reproduce:
I was running dbench 32 on an ext3 partition without htree, and was running ab
(apache bench) on the local webserver, 200 concurrent connections to a php
script. The system survived the oops. All filesystems have been fscked within
the last 5 days. After the oops, a forced fsck shows all filesystems are clean.
All ext3 filesystems are mounted with "defaults,noatime,errors=remount-ro"
options.
