I wanted to add that I've seen similar hard-lockups (can't even drop into
DDB via the serial console, it's so frozen). I've also seen it
"almost" lock up, where the IDE activity light would be on solid, yet there
was no IDE activity. When my machine freezes, it usually has the IDE light
lit solid (makes a visual "is it locked up" check easy!). :-)
I can't correlate the lockups to specific tasks, as doing lots of
SMB traffic, and many concurrent builds doesn't seem to tickle the lockup.
My machine is a dual P3-600EB with 512M of RAM. While this is a pretty
generic "me too" report, I wanted you to know that you're not alone. :-)
(And yes, running in !MP mode makes a stable machine, although my box
currently seems to run ~15 days between lockups.)
