Oh crap. It's back. I don't know what's different from before, but the system now locks up again exactly the same way, even with the lock contention fix applied.
With or without CONFIG_PROVE_LOCKING=y in the config. I've gotta get some work done here (this is my primary development machine), so it's back to CONFIG_DETECT_SOFTLOCKUP=y for a while. If anyone has a patch to dump out state/whatever just before that last message that preceeds all lockups, then pass it along and I'll queue it up for testing as soon as I can.
