This is the fix for this from Arjan:

    ACPI: Reject below-freezing temperatures as invalid critical temperatures

    My laptop thinks that it's a good idea to give -73C as the critical
    CPU temperature.... which isn't the best thing since it causes a shutdown
    right at bootup.

    Temperatures below freezing are clearly invalid critical thresholds
    so just reject these as such.


btw on my laptop, it wasn't 0 that was returned, but 2007.
This is suspected to be related to how windows finds some random other ACPI state to return,
but it significantly was an AML issue on the bios side.
Just the effect was a trainwreck so I added a check to the kernel (in addition to getting
full info to Robert for the ACPICA side of the issue).
