First, let me say that there is a tutorial already in the forums for undervolting, however it is geared more towards the Indel Dual Core processors. So I started searching for a way to do so on my AMD Sempron processor for my laptop.
I was hitting a brick wall so I checked with the #ubuntu IRC channel and ran across a person that pointed me to this How To:
I tried following those directions and ran into the issues and so I searched for more info regarding the problem I was having. I ran across this How To:
Both are basically the same but I thought I would post them just in case there are any questions regarding the process. However I am running into an issue with one of the commands that is supposed to be run.
Each how to says to run this command:
But when I do that I get the following:
patch -p1 < ../linux-phc-0.3.0/kernel-patch/linux-phc-0.3.0-kernel-ubuntu-2.6.20.patch
I dont know which file it should be patching. Im assuming the kernel file, but Im not really sure and hoped that someone here could help me out with some guidance. Im trying to find the answers and googling and searching but not coming up with much.
:~/undervolt/linux-2.6.24$ patch -p1 < linux-phc-0.3.0-kernel-vanilla-2.6.23rc3.patch
can't find file to patch at input line 4
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

I would appreciate any assistance.
