I got a Pentium Dual Core E5200 on a Gigabyte EG43M-S2H and installed os2009.06
on it.
My problem is, that it is always running at the max speed (2.5 GHz) instead of
switching to one of the lower frequencies, which are listed under
supported_frequencies.
Is my CPU not supported or is there something I can do?
power.conf has these two lines:
cpupm enable
cpu-threshold 1s
kstat cpu_info looks like this:
