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.
