:I have a system using a fairly new Supermicro MB, with 2 P3-1GHZ, and 512mb
:ram. Running stable works fine at least a day or so with LOTS of activity.
:Running current it hangs (with no output of any kind, and apparently all
:interrupts disabled) so DDB does me no good... This requires a fair amount
:of activity (usually will hang in make -j3 world with 2 copies of
:setiathome -nice 19) Time to hang varies from a half-hour to a couple
:of days; hardly ever longer.
:
:Maybe I need an NMI button (or does that work?)
This could be a priority inversion issue. Try running setiathome at
nice -10 (or not running it at all), and see if you can still crash
the box.

Try turning off ACPI.
