Ok, this afternoon I was definitly running a kernel with that patch in it, and managed to get a trace (It was the one from the top of this thread that unfortunatly got truncated). Now, I can't reproduce it on a plain 2.6.18+that patch. I'll leave the stress test running overnight, and see if anything falls out in the morning.
