analyzing CPU 0:
driver: powernow-k8
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 14.0 us.
hardware limits: 800 MHz - 2.90 GHz
available frequency steps: 2.90 GHz, 2.20 GHz, 1.70 GHz, 800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 800 MHz and 2.90 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 2.90 GHz.

Суть проблемы что после перезагрузки значение в /sys/devices/system/cpu/cpuX/cpufreq/scaling_min_freq
Пока выкрутился, добавив изменение scaling_min_freq в rc.local. Но непонятно почему сбрасывается на максимальное. Ubuntu 10.04
