The timer interrupt is incrementing very slowly. Instead of 1000 Hz it's incrementing about once or twice per minute. What would cause that? I had ntpd running, but I killed it.
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.

When I got to work, I found that X-windows had failed to start after downgrading to the 2.6.12 kernel. So I tried 2.6.14 and noticed that udev failed to start. So I had to bring the kernel back to 2.6.16. I compiled 2.6.16.20 without ACPI and APM support and I'm trying that now.
I have not seen the timer problem since I changed to the 2.6.16.20 kernel. I've filed a bug report against the fc5 kernels:

Thanks to everyone for their suggestions...

PS - I'm not sure whether to add "resolved" to the subject line because this solution is just a workaround.
