I experienced the very same thing two weeks ago with (then) FreeBSD 4.1 BETA. It could not have been a powerfailure, the monitor hanging on the same outlet still had power. I suspect it is a hardware problem, maybe a bad power supply. Healthd showed, that my power supply indeed delivers very unstable values. If this does not happen again, I am happy. If it does, the first thing I'll do is buy a better power supply. Of course that doesn't help you much, but I wanted you to know that you are not the only one with this problem. cheers, Tobe On Thu, Dec 07, 2000 at 01:00:09PM +0800, tanbin wrote: > Since 3 days ago, our freeBSD box has automatically power-down-then-up 3 > times.
