Hmm. Eric - mind testing current -git?
J. R. Okajima found a possible problem with the new RCU filename lookup, which could corrupt the filp_cache. I'd expect the normal result to be an oops, but maybe there could be memory corruption. And the easiest way to trigger it would probably be to have lots of concurrent fs activity with renames.
Now, it's not new to -rc4: the whole rcu lookup thing was merged into -rc1. But since I still don't see anything that looks likely to be introduced after -rc3, it might not hurt to think that maybe it's just rare enough that you just thought -rc3 was ok, and then you were unlucky with -rc4.
