Kuki Linux 2.8 has the acerhdf module included to control the fan speed. For most people, it seems to be working well. For some, particularly those who may have upgraded their bios, it sometimes fails to load.
If you fall into that category, where it fails to load, if you would open a terminal window and issue the following commands:
sudo rmmod acerhdf
sudo modprobe acerhdf verbose=1
And then copy and paste the output from the last command and post it here in the topic. I will see that the developer of acerhdf gets the output so he can work on what the problem is.
With regards to the actual problem we are looking into, acerhdf fails to load at all and gives an error message about an unsupported bios. It seems that if your acer came with bios 3309 (for example) things work. If you upgraded to bios 3309 (for example) then they don't work.
Please keep this topic only related to this one issue.
