I've set /proc/acpi/ibm/fan to "disengaged" - which causes the fan to run at full speed without any hardware or software control. My idle temps are way down, but I am still periodically experiencing the thermal shutdowns - usually while processes are running with the laptop unattended. The fan speed helps, but has not solved the issue for me.

I've submitted apport-collect data above.

Note that on my Lenovo T61, 2000-3000 rpm is actually normal by design - which contradicts my earlier assertion that the fan was running too slowly. Disengaged, the fan is currently running 4000-5000 rpm (which as I said helps a great deal but hasn't solved the issue entirely for me)

I can replicate the issue using the stress application (see earlier posts)

I tried to replicate the issue on another laptop running 8.04 Hardy (32-bit in that case) and was not able to do so.
