[Bug 36014] Re: kernel can't scale cpu frequency

[dragomirov]

Hi, I know I came late in this discussion. After upgrading to Edgy, my freq. scaling broke down. And my processor runs at full speed  all the time (I have a Dell Inspiron 5160, P4 3.06 Mhz).
I got this bug with both 386 and generic linux image 2.17 branch (neverthless to say that with Dapper and 2.15 everything was going fine).

I solved the problem re-installing powernowd (I'm not actually sure if it's necessary) and adding by hand the p4-clockmod module to the kernel by:
sudo modprobe p4-clockmod

and adding it to /etc/modules file.

Hope this can help someone
