I installed Fedora 11 and I'm getting the same thing there, too (kernel
2.6.29.6-213.fc11.x86_64).
What can I do to help fix this?

Anywhere from once every two weeks to two times daily I have to
power-cycle a system due to a CPU getting this "soft lockup". It
happens both with and without "noapic".
Please see the attached syslog information that appears when it occurs.
How do I debug, and how can I assist whoever is able to fix this?
(I'm not subscribed to the list, so please CC me on replies.)
Thanks,
Lee.
