There's your answer - kernel bug specific to your hardware.
Try downgrading your kernel to an earlier release, and see if the timer
(and other issues) disappear.
OK, I downgraded to 2.6.12 and let it run overnight. Oddly, the timer
was getting 4 interrupts per second this morning. The overnight
average was about 20 interrupts per second, which might mean
it ran for 7.5 minutes at 1000 Hz and then switched to 4 Hz. However,
the date/time reported is correct, unlike when my system was "hanging"
before.
The system seems pretty fast and responsive, but I think top is
under-reporting the CPU usage by different processes. Processes
that usually suck a lot of CPU are reporting less than 1%. Are there
any kernel compatibility compatibility problems with running 2.6.12
with fc5?
Thanks...

PS - Since my problem was intermittent, I'm not sure if it has gone away.
I still am seeing something weird wrt the timer interrupts.
