Hello. I've got very similar problem with my Thinkpad T61. Under 8.10 laptop halts with "Critical temperature reached", even if it's quite idle. Fan works all the time, if computer gets hotter - fan becomes faster, so acpi works ok. It's set to 'auto' mode. Halts are quite random, sometimes without significant load average.. Today it halted while writing someting on the gnome-terminal with browser opened and temeratures about 60 C. (got sensors aplet with core1/2 and nvidia temerature). It happens also while watching HD movie (halted in the middle) and while playing games (halted on quake3 or need for speed). Tried to use tpfand to speed up fan when temerature becomes too high, but it made halts to show up more often.
Strange things are happening with fan control..

Under 8.04 it behaves normally. Don't know if it's related, but might be..
