I'm not a driver/kernel developer, nor do I know C, nor can the box spare the downtime in the event of this situation occurring again. Further more, since the box continues to run, and isn't a true "hang" in the sense of the word, thousands of instructions will have run after the true cause of the problem, making debugging even harder (presumably - as I say I'm no developer!)
