These locks are particularly frustrating as they leave no trace in the
logs. the logs just stop until they come up from the reboot. I've seen
it happen while I'm working maybe two or three times... just lock
right up and be totally gone. screen looks fine, nothing responds, no
ssh, no response to keyboard (capslock/numlock frozen) etc. Sometimes
even the restart button on the box won't work and I'll have to force a
shutdown with the 4-second power button press. So I have no doubts
that its locking up tight. This is part of why I think it might be
related to that acpi stuff as it seems to happen a lot when I'm NOT
working at it. perhaps the bios is trying to suspend something and it
causes a problem?
I actually had a suspiciously similar problem recently. A couple of
times, everything just froze. The power button was the only thing
that would respond. memtest86+ showed no problems. I figured it
might be a bad block in swap, so I ran the START self-diagnostics on
the drive. The only effect that had was to do something bad to the
drive R/W head, reminding me that I really should be doing backups.
