Subject: 2.6.36-rc7 continuos kernel panics due to of cpu_idle (and cpu_intel_idle)

Hi All

I have strong suspects around CONFIG_CPU_IDLE setting provoking
several kernel panics. All panics have the cpu_idle function involved.
I don't know how to reproduce, it happened every 2-3 hrs using firefox browser.

System with 2.6.35.5 is totally stable.

I took a snapshot of a panic here:

Situation is dramatically worse when CONFIG_INTEL_IDLE is set.
Here panic happens even during startup.

I'm using a x64 core2 processor.
I'm ready to provide more infos/test patches.

Regards,
