Bug Description

I upgraded to 2.6.10-5 kernel in hoary and after that powernowd stopped working.
CPU frequency scaling not supported is the output of sudo /etc/init.d/powernowd
start
Before upgrading powernowd was working "correctly" (it only showed wrong freq
values but scaled fine)

Hi, the frequency scaling seemed to work in hoary until I reinstalled it with
the preview release.
Running kernel: Linux ki 2.6.10-4-amd64-generic #1 Thu Mar 10 02:52:25 UTC 2005
x86_64 GNU/Linux

herman@ki:/etc/init.d$ sudo ./powernowd start
 * Starting powernowd...
 * CPU frequency scaling not supported

herman@ki:/lib/modules/2.6.10-4-amd64-generic/kernel/arch/x86_64/kernel/cpufreq$
sudo modprobe powernow-k8
herman@ki:/lib/modules/2.6.10-4-amd64-generic/kernel/arch/x86_64/kernel/cpufreq$
sudo /etc/init.d/powernowd start
 * Starting powernowd...

And everything works agian \o/

Sorry there is something not clear to me.

Using 2.6.10-4 you have to modprobe powernow-k8.

What if you do modprobe with 2.6.10-5 ?

You can safely install the 2 kernels in parallel to test. -5 won't overwrite or
cancel -4.

Please confirm that the init script works correctly with an up-to-date hoary.

Here on k7 system (hoary):
with -4 kernel all works fine
with -5 kernel powernow-k7 stopped loading automatically; modprobe loads
correctly the module (powernow_k7) and enables frequency scaling.

I confirm the problem is solved in an up to date hoary (amd64 arch).
