Hmm, no I'm not worried about old filesystems on the disk.  I thought
maybe you were running the tests on the same LV, and creating new
filesystems on a single LV between the tests.  What I'm worried about
is old inodes being kept in memory between the tests.  If the tests are
being run on separate LVs, then that is not a possibility.

I guess what is needed is a real oops report from the ext3 problem.
Maybe Andrew or Stephen can figure it out.

Cheers, Andreas
