The timer interrupt is incrementing very slowly. Instead of 1000

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.
Apparently all bugzilla changes in the last week were lost, so the
bug report I filed on this issue has disappeared. What I learned
so far was that the IBM ThinkCentre had a buggy BIOS, so they asked
me to update it, which I did. I'm trying to run the default fc5 kernel
now with the updated kernel. Apparently newer kernels use more
of the ACPI features than older kernels and they suspected that
a buggy BIOS was to blame.
