Here's the ksymoops output:

I'm thinking that this is probably caused by bad hardware, since the
system ran fine for a couple months until a bunch of problems started
cropping up. I figured I'd post this to the list anyway though, in cause
somebody has other ideas. My first step is going to be to replace the RAM
in the box.

By the way, this is a pentium with stepping=5. I have not yet tried the
mem=nopentium option.
