It sounds a lot like a version of this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=474624

Can you confirm if the output of the command "dmesg" reports something
like the following?

irq 16: nobody cared (try booting with the "irqpoll" option)
Pid: 0, comm: swapper Not tainted 2.6.27.7-134.fc10.x86_64 #1

Disabling IRQ #16

If so, I think you see a duplicate of that bug.

Best,
