This was a recent discovery, I don't think the patch is even in an aa kernel yet ;-) Since Xuan's stack trace had things waiting in deactivate page, it sounded similar to the problem andrea described. We had a few test boxes hanging under load, they are testing the patch now, plus Xuan, plus one other l-k user. If their problems go away, we'll have to dig to find the exact corruption. -chris
