Some sort corruption of my Thermal Subsystem after suspend to ram

[Gabriel C]

Hi all,

I thought I've found all issue with that new box but I was wrong ;)

On an ASUS P5E-VM DO , 4G RAM , Q9300 CPU after suspend to ram Thermal 
Subsystem gets corrupted in some way.

I got some reboot , halt problems and was hunting the issue and noticed these problems only
occurred when I've suspend the box to ram , at least once.

I've tested 2.6.{24*,25,linus-git(before ACPI merge),x86-latest-git} and all got that problem.

Also on x86-latest-git I've tested with MTRR_SANITIZER on/off. It does not make any difference.


lspci output before s2r is :
