Hello, Since ubuntu 11.10, some thinkpad computers suffer from overheating and reboot (due to excessive heat). You can follow the bug report here: <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689> After changing thinfan speed level, the problem stays. I've been trying some solutions but no clue for now: <http://askubuntu.com/questions/133030/overheating-and-reboot-with-ubuntu-11-10-and-12-04-on-thinpad-t500> A recent comment in the ubuntu bug report shows a linux bug with the same effect and its resolution on acpi: <https://bugzilla.kernel.org/show_bug.cgi?id=42858> sadly, this fix is already present in Linux 12.04, but correct me if i'm wrong, the acpi managment is different for thinkpad, no ? If yes, could be this linux bug present in the thinkpad_acpi module ? Anyway, if you have any idea how to diagnose the problem, i'm ready to help. Thank you.
