Comment 7 for bug 670707

Just to add that I'm also seeing this problem under Ubuntu 11.10 on the L300D.

I think the fan is usually off upon first booting.
When I suspend and then resume again the fan will turn on and stay on.

When the machine is too loaded, it will overheat and just power off (very annoyingly, one time, causing my filesystem to be mostly trashed).

Happy to investigate further, but really have no idea where to start. I'm guessing the fan control for this model of toshiba laptop needs a little reverse engineering work - anyone have any pointers on where I should start looking? Disassembling ACPI tables?
