Still sounds like some kind of hardware problem, because it runs fine as long as it isn't under pressure and fails in a different way each time. If it's always the same CPU, that may be a hint. Bad RAM is the most frequent culprit for such unpredictable problems, though. If you have the opportunity to disable SMP and try again (e.g., you have a GENERIC kernel around that matches your userland), that would be worth a shot.
