The critical temperature for the shutdown should still be logged in: /var/log/messages Can you grab that one out, please. But from what we know, this sounds like a real overheating and not a wrongly read value, also thinkpads used to have a switch to let the temperature jump above the critical trip point under certain conditions. This seem to be the case on THM0 (I remember 127 C...): /proc/acpi/thermal_zone/THM0/trip_points:critical (S5): 127 C Can we be sure it's because of the fans? 2.6.31 works? Also the latest stable one? Then this one might be unrelated (11.2, 2.6.31.X based, Acer Aspire 5315): [Bug 557850] System Fan is being stopped on boot, CPU goes overheated and shut down instantly https://bugzilla.novell.com/show_bug.cgi?id=557850 Thomas
