Hmm, I don't see my similar report on 2.5.2-dj7 in the archive.
Basically the exact same behaviour I got with 2.5.3.
Between 2.5.2-dj7 and 2.5.3 runs; 2.4.17 and 2.4.18pre7aa1 ran
the same tests without a problem.

Here is the report on 2.5.2-dj7:

I got the following oops on 2.5.2-dj7 during the "runtests"
benchmark.  The logfiles suggest it was after dbench 192
completed on ext2, but before the next test (LTP) got
started.  I.E. in the "echo;sync;sleep" part of the
"runtests" wrapper.  Filesystems are reiserfs other than
the one that runs dbench.

It did not reboot.  It does appear livelocked though.
2.5.2-dj[1-6] completed the tests with no problem.
