That did seem to get rid of the original error. However, I'm now
experiencing a reiserfs4 panic so I'm not 100% confident the problem
really is gone, but the reiserfs panic isn't anywhere as near hard as
the panic's I have been experiencing; I was able to reboot the machine
even though the tests were not completing correctly. Full panic for
that one is below:
Get the same exact panic on ia32 NUMA-Q (just posted it, but for
reference, there's a copy here:
http://test.kernel.org/abat/34623/debug/console.log
). But only in -mm3, not -mm2, so
probably it's intermittent if you were already seeing it on -mm1?
PS. I think the reiser4 thing was a typo, it's generic by the looks
of it, and I don't think we test reiser4, is probably ext3 or 2.
