View Full Version : acpi_cpufreq error on xeon based machine.

28th November 2006, 10:35 PM

I have installed FC6 on a Dual CPU (Xeon 5130) based Dell Machine. When the machine boots up I get the following error. I have updated the Kernel to 2849. I want to do CPU speed Scaling to run the CPU at lower speed when not loaded.

FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.18-1.2849.fc6/kernel/arch/x86_64/kernel/cpufreq/acpi-cpufreq.ko): No such device

Also I changed the /etc/cpuspeed.conf file to replace the DRIVER="powernow-k7" to DRIVER="p4-clockmod". When I do modprobe on this module, it is giving me error "FATAL: Module p4_clockmod not found."

What is the correct setup to have the ACPI enabled on this Machine....

I'm also getting the same error ... Any solution will help a lot...

My solution may not be what you're looking for but you can always do system-config-services then edit runlevel all, turn off cpuspeed and save. Unless you're on a laptop or really concerned about energy conservation.

I get the same error with an AMD Sempron 64. I never had a problem with FC5 x86_64, it seems new in FC6.

The only solution I found was to disable cpuspeed since it obviously wasn't working anyway. I would like a cleaner solution if one is available.

I don't know if there is one unless the problem is caused by having the wrong kernel installed by Anaconda, but on a Desktop machine this really isn't needed anyway.

I you are using desktops just remove it

su -
yum remove cpuspeed

and another no you dont need

yum remove apmd

these are for laptops and are not needed

This problem is not just with 64 bit as im running 32bit on my laptop and am also getting this error. There is a report of it at bugzilla bug #183681. Looks like it first poped its head up on FC5 test 3

The odd part for me was I had FC5 on this same laptop and did not have a problem with it didnt show up untill I did a fresh install of FC6.

Thanx leigh123

This problem solved by updating cpuspeed.

Yeah, the new cpuspeed update I got today (12/14/06) seems to have resolved the problem.

If you uninstalled it and want it back (power saving or whatever), just do a 'yum install cpuspeed' and you should be good to go.

Is there a specific repository that cpuspeed is in, because when I do a "yum install cpuspeed" it says "Nothing to do" but when I type in "cpuspeed" I get this:

Error: Could not open file for writing: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Error: No such file or directory

Sorry, just installed Fedora...

I you are using desktops just remove it

su -
yum remove cpuspeed

and another no you dont need

yum remove apmd

these are for laptops and are not needed

When i try either of these commands i get this:

Existing lock /var/run/yum.pid: another copy is running. Aborting.

When i also go to Applications/System Tools/Software updater i get this: Another application is running which is accessing software information and all i can do is click ok.

Any ideas? Thank you in advance.

Ok problem solved by going to System/Administration/Services and i unchecked yum-updatesd.
