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: 8.0 us.
hardware limits: 1.40 GHz - 3.60 GHz
available frequency steps: 3.60 GHz, 3.30 GHz, 2.50 GHz, 1.70 GHz, 1.40 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 3.60 GHz and 3.60 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 3.60 GHz (asserted by call to hardware).

# dmesg | grep powernow
[ 1.220576] powernow-k8: Found 1 AMD FX(tm)-4100 Quad-Core Processor (4 cpu cores) (version 2.20.00)
[ 1.220596] powernow-k8: Core Performance Boosting: on.
[ 1.220636] powernow-k8: 0 : pstate 0 (3600 MHz)
[ 1.220640] powernow-k8: 1 : pstate 1 (3300 MHz)
[ 1.220643] powernow-k8: 2 : pstate 2 (2500 MHz)
[ 1.220645] powernow-k8: 3 : pstate 3 (1700 MHz)
[ 1.220648] powernow-k8: 4 : pstate 4 (1400 MHz)Пробовал разные сочетания cool'n'quiet, Core C6 и C1E. При выключенном cool'n'quiet регулировка вообще недоступна. От остальных параметров вроде не зависит. Характерно что при загрузке cpufreq stats: 3.60 GHz показывает что-то в районе 98,00% - 99,00% - т.е. на ранних стадиях загрузки видимо пашет, а потом перестает. Всякие cpufreq-set -f 1,4GHz проглатывает молча, при этом ничего не меняется.
