Martin,
Thanks for verifying that Windows also observes the huge temperature jumps
that we see in Linux.  It could be that the cooling hardware has become
intermittent, or that the EC/sensors on this box are not reliable.
In either case, it is good to know it isn't a Linux specific issue.

Also, thanks for verifying that Windows too can overheat
and shut-down this system.  This suggests that Linux does
not have an inherent disadvantage vs. Windows in this area.

ACPI: move thermal trip handling to generic thermal layer

thermal: support forcing support for passive cooling

Indeed, Matthew's patches above make Linux more robust
than Windows on this box.  Please let us know what you experience.

Note, however, that throttling is a last resort solution.
The best it can do is to make your system run slowly
to prevent it from shutting down.  If you want your machine
to run fast under heavy load, it will likely require some hardware
maintenance.
