Bug Description
Binary package hint: linux-image-
This bug relates to https:/
When I log into Gnome, the CPU Frequency Scaling Monitor tells me, "CPU frequency scaling unsupported. You will not be able to modify the frequency of your machine. Your machine may be misconfigured or not have hardware support for CPU frequency scaling."
It seems as though the problem lies (in part) with the inability to load the acpi-cpufreq kernel module. It is physically present:
$ ls -lh /lib/modules/
total 64K
-rw-r--r-- 1 root root 25K 2009-01-29 15:52 acpi-cpufreq.ko
-rw-r--r-- 1 root root 35K 2009-01-29 15:52 powernow-k8.ko
But I cannot get the kernel to load the module:
# modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/
I am able to compile my own kernel (2.6.27.10 from kernel.org) making some changes to the 2.6.27-11-generic config file (basically disabling some debugging options which cause my debs to be HUGE if I go with the standard config-
FYI, here is the guide I used to compile my own kernel: http://
I will say that the dmesg gives a ton of ACPI Errors when I boot into the stock kernel. This is in stark contrast to the custom compiled kernel I'm using wherein there are not ACPI Errors at all and cpu scaling works just fine.

Same problems here.
Well... I mean, it`s not like it`s some stupid GUI bug... How can you be serious about the server market?
