everything to always on.
Also, do you have a UPS power supply? Is your VCR
blinking?
Yes, the whole thing's on a UPS. I adjusted all the appropriate sleep and
suspend settings. Its console is attended, and I ssh in. It does not go to
sleep on its own.
This is a hardware fault, somewhere. I doubt that it's the video card, but I
have a spare on the way. It's either a bad motherboard, a bad CPU, or an
incompatibility between the motherboard and the CPU. I swapped the CPU, and
I have nothing to do but fiddle my thumbs for the next two weeks.
