2.5.73-mm1 falling over in SDET

I tried sdet on 16-way numaq with 2.5.73-mm2. It completes the run on ext2 
(no OOMs), but gives following oops while running on ext3

Looks like that was some one off oops.. on second iteration I could run
sdet on ext3 also without any oops or oom.

No, I think that assertion failure in journal_dirty_metadata() was more
than a once off, whatever that is.  There is probably something wrong in
there, but from a moderate-sized look I cannot see what it is.

Unless inspiration strikes we will need to wait until someone can hit it
with some sort of repeatability and then run with the ext3-debug patch
applied and enabled.

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.73/ext3-debug.patch

This will give a trace of what happened to that buffer and should allow me
to fix the bug.

Interesting CPU number.

The mangled output is supposed to be fixed.  Looks like it
only partially worked.  Why doesn't someone fix this?

No, it ain't a lot of use really.  Is it repeatable?  If
so does changing elevators make it go away?
