Is my system compatible to have cpufreq ? If yes, what steps sshould I follow to install cpufreq ? When I entered BIOS settings, I was not able to view option to change CPU performance settings either.

Hi,I'm trying to set up frequency scaling on my Intel i5 760 as per the wiki.The only problem is I can't seem to load the acpi_cpufreq module!# modprobe acpi_cpufreq FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.39-ARCH/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko.gz): Input/output errorThere is no additional output in dmesg from this error.I'm running x86_64 btw, and I notice that it's trying to load an x86 module, could this have anything to do with it?Thanks!

HiDid you find a solution? I'm having exactly the same problem with acpi-cpufreq. (eeepc 900). I tried modprobing the p4_clockmod as well, which some older posts say is required for my machine, but I got the same error.

From his error message it looks like he's using the same as me, ie 2.6.39-ARCH (which seems strange since it seems to have only been released today in the ARCH repositories). Based on your hint I am going to try booting into 2.6.38 fallback and see if I can install it (my other machines on 2.6.38 have it installed).Edit - My fallback kernel is also 2.6.39. Tried modprobing anyway and got the same error. (Strange re 2.6.38/39. I Suy'd one of my other machines today, a few hours before Suy'ing this one (which resuted in new kernel install) and that other machine is
