Comment 7 for bug 10813

I have a Dell Lattitude C600 with a P III Coppermine 1 GHz.

Powernowd determines the CPU and loads the speedstep-smi module.

From then on I have a 1 second system freeze everytime the cpu frequency is
changed (correlated using the Gnome Applet).

In fact, the Dell has a weird BIOS, which takes care of frequency changes
itself, thus the clash with the kernel Speedstep.

Without Powernowd, I can still witness frequency changes between 20 and 1002 MHz
using the x86info module from gkrellm.

Here are the outputs that powernowd uses on my machine in order to determine the
CPU type. It may be useful in order to change the
/usr/share/powernowd/cpufreq-detect.sh script so that it detects machines like
mine properly.
