Actually, we've had that occasionally, on a number of boxes. I *think* they were all SuperMicros (sold by Penguin), and they become unresponsive - when I plug in the monitor-on-a-stick, there's no response at all on the console, keys do nothing. we have to power cycle them, and nothing ever shows, not in dmesg.old, not messages, nowhere. Never figured it out. mark
