Comment 35 for bug 370173

What was VERY scary was that the following lines started showing in my /var/log/messages...

... and *didn't* shut down.

This happened a lot when the lappie overheated... I've got Linux Emporium investigating it as well (preinstalled machine from them).

Looks as though it's known about... http://marc.info/?l=git-commits-head&m=123213959414589&w=2

In both cases - the fan ought to kick in and run at close to max speed - it doesn't. Only speed up from, say 3003rpm to 3050 for a few seconds. I'd have expected to feel the fan really ramp up and run at abotu 4000-5000 or even max out (I think they're rated to approx 5500rpm for a long time ot get the temp right back down before slowing back down again. Hence the cooler...

I use this thing as a desktop replacement, so often run it without the battery on mains, and often all day.
