Speedfreq only with USB mouse?

[kahless23]

Hey...

I installed speedfreq and ACPI on my Fujitsu-Siemens Lifebook E4010 according to the Acer Travelmate Howto-Wiki.

Speedfreq works fine, but only as long as I have my USB-mouse connected. When I disconnect the mouse, the CPU runs constantly at 1600MHz.

I tracked the problem back to /proc/stat, where the kernel counts its idle-time. Speedfreq is reading it from there. Now if I disconnect the mouse, the kernel seems to count very slow. And this affects the way speedfreq adjusts the CPU.

Anybody understood what I mean...?

Anybody seeing the same beavior?

This behavior is odd, because usually I disconnect the mouse when I'm not connected to AC power. And that is the situation a power management would be useful...

Parameters:
- FSC Lifebook E4010 (Centrino, Pentium M 1600)
- Kernel 2.6.8-gentoo-r7
- Speedfreq 0.7.2


Ciao,
Ronald.
