FATAL: Module acpi_cpufreq not found


I have a boot up message that says:

FATAL: Module acpi_cpufreq not found

I am using...

[root@localhost ~]# uname -r
2.6.18-1.2849.fc6xen

xen was what was automatically installed from the DVD,
and an update brought it to the 2.6.18-1.2849.fc6xen kernel.

The only thing I found (That I could understand) was at
this site >>> linuxquestions.org/questions/showthread.php?t=500080[/url]

I tried what was on the thread, and below is what I got.


[root@localhost ~]# /sbin/modprobe acpi-cpufreq
FATAL: Module acpi_cpufreq not found.

[root@localhost ~]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies: No such file or directory

[root@localhost ~]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors: No such file or directory

[root@localhost ~]# modprobe cpufreq_ondemand
FATAL: Module cpufreq_ondemand not found.

[root@localhost ~]# rpm -q kernel --qf '%{ARCH}\n'
package kernel is not installed

I don't know if what I have is a i586 kernel. There's a i686 kernel and there's a xen kernel.
Did the xen come with a i586 processor kernel?

I have a Dell with duel xeon processors.

Can someone walk me through this please?

I found a simple answer at this thread
//forum.fedoraforum.org/forum/showthread.php?t=139338&highlight=Fatal%3A+Module+acpi_cpufreq
[add http: in front of the above]

#yum remove cpuspeed
#yum remove apmd

It seems as long as the computer that's being used is NOTa laptop, you don't need these two programs.

Ok, cool. Unfortunately my FC installation is on my laptop, but I am sure this solution will help others.

I had to go to a SMP kernel version on my laptop before cpuspeed would work.

I thought the only reason for running a XEN kernel was to support several virtual sessions using different distributions. Is that what you're doing?

<edit>Oh, my laptop is an old Gateway with an AMD 2200 cpu, not a 64 bit system.</edit>

I had encoutered the same problem when finished my FC6 installation using the default kernel with Xen and the problem had been solved when I updated my kernel to kernel-2.6.19-1.2911.fc6 .(without Xen).
One possibility for solving this problem is by updating the kernel,the other possibility may be that kernel with Xen does not support cpu scaling.

I had the same problem from fresh install without the Xen kernel on 64 bit FC6, eventually there was an update that fixed it, did'nt have to worry to much as I did not see any ill effects from it before the update came out.
