FC5 Upgrade: CPU Temperature/Thermal Lockup

[Greg Kilfoyle]

I'm still fighting with this. I spent many hours building a new kernel
from the source RPM with CONFIG_ACPI_THERMAL disabled. This kernel still
locks up in the same way.

Does anyone know if I need to de-configure CONFIG_X86_MCE_P4THERMAL too?

You're probably wondering why I don't just get the motherboard replaced
again. Because they won't perform any warranty work unless it is a
Windows issue (because that's what the laptop came installed with).

I guess I'll kick off another 6 hours of kernel building with
CONFIG_X86_MCE_P4THERMAL disabled, but it would help if someone had some
insight for me, rather than just taking stabs in the dark.

Cheers, Greg.
