Bug Description
This afternoon have installed Feisty on a Macbook Pro 15, core2 duo.
The MBP was really hot so I changed fan minimum speed this way:
sudo sh -c "echo 3000 > /sys/devices/
and the temperature was cool.
Then I upgraded to gutsy, changing feisty --> gutsy in source.list and upgrading the system via apt-get. Everything was good but the Macbook was still hot so I retry but
1. there was no applesmc
2. I made: "sudo modprobe applesmc"
3. I find applesmc under:
cat /sys/devices/
Ok for new "location" applesmc.768, but I suspect something is wrong in fact even with fan_min at 5/6000 the temperature is high, much higher than in the afternoon with 3500. Maybe something is missing. Any idea?
How may I check if appleair is loaded, too?
Same problem with current hardy and intrepid.

I also have a MacBook Pro 15" Core2Duo (mine is from november 2006, I'm not sure about yours).
applesmc is loaded automagically at startup (which is great). www.phoronix. com/forums/ showthread. php?t=3130 for the semi-official explanation).
The laptop is also very hot sometimes, it comes from the ATI GPU (Radeon X1600 Mobility), which oddly doesn't support powersaving under Linux. At the moment, there is nothing we can do about that. ATI/AMD is aware of the situation and does nothing (see http://
After your upgrade from feisty to gutsy, have you also updated your linux kernel image to 2.6.22 ? (the package is linux-image- 2.6.22- *). I remember I had to do it manually in my case. This new version contains many fixes to applesmc.
