Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: speedstep-ich
CPUs which need to switch frequency at the same time: 0
hardware limits: 1.20 GHz - 1.60 GHz
available frequency steps: 1.60 GHz, 1.20 GHz
available cpufreq governors: conservative, ondemand, powersave, userspace, performance
current policy: frequency should be within 1.20 GHz and 1.60 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz (asserted by call to hardware).

| I think you're cpufreqd is using the ondemand governor, which means that you'll get the 1.6GHz when it feels like it needs it, otherwise it'll just run at 1.2GHz. |
