Comment 6 for bug 63439

I just found out sth which makes my CPU work with F17 on 1.83 Ghz:

Add the following to a startupscript:

echo 1833000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 1833000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor

it seems that you have to set the governer again after setting the scaling_max_freq.

cpufreq-info output is:

root@mephtop:/usr/src/linux-2.6.19.1# cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006

analyzing CPU 0:
  driver: centrino
  CPUs which need to switch frequency at the same time: 0
  hardware limits: 1000 MHz - 1.83 GHz
  available frequency steps: 1.83 GHz, 1.33 GHz, 1000 MHz
  available cpufreq governors: userspace, powersave, ondemand, conservative, performance
  current policy: frequency should be within 1000 MHz and 1.83 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 1.83 GHz (asserted by call to hardware).
