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?

Thanks,

Lee.
