The problem with coretemp is you can't just disable it, it has a system driver
associated with it. To test that one you will have to completely remove.
This is really my last shot at this, I can't get a more specific trace than what I've already described.
We know this is a driver issue sadly I'm just not able to point it out.
Everything in you driver list is a proper windows 7 driver, power state issues are still a bit of a problem.
Have you considered just changing the power scheme to avoid hibernation?
