Oh boy, that must be the second time in a decade that I see that codepath triggering. It is the second-level alert that the ThinkPad is about to catch fire. It should have logged a "is too hot!" first-level alert earlier, but this depends on the EC and not the driver. Maybe the temperature raised too fast. In Windows, the system would attempt to hibernate or shutdown. I would be quite happy to have thinkpad-acpi trigger such behavior as well, patches (or guidance) are welcome ;-) Anyway, if that temperature goes about 1~2°C higher, the EC should cut power to your motherboard. Apparently, the built-in thermal protection clock modulation on the Intel processor is somehow saving your box from that forced power-off. -- Henrique Holschuh
