So that kernel works with my testing but the module doesn't auto load the cpufreq-cpu0 module. If you do: modprobe cpufreq-cpu0 You then get: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 300000 600000 800000 1000000 Even with 3.12.8 you can manually load that module and it works but you only get up to 720mhz.
