No ideas... and I've had a number of systems do this, over the last couple
years, where someone noted it had stopped responding; I go down, and it
doesn't respond *at* *all* when I plug in a monitor & keyboard, and power
cycling's the only answer.

Thinking about it, I believe it's mostly been on our Penguin servers, and
that co. uses Supermicro m/b's, and we've had h/w problems with them,
also, and have had several m/b's replaced under warranty.
