Also, "Oops during closedown with 2.6.35-rc3-git3" is an
iterate_supers oops (in the jpg) and Chris says it's repeatable for
him.

Chris - you could try testing current -git now that I've merged Nick's
patch. It's commit 57439f878af ("fs: fix superblock iteration race"),
and I just pushed it out (so it might take a few minutes to mirror out
to the public git trees, but it should be there shortly).
