check for the right governor (ondemand) you shouldn't care. in some cases
though you must set yourself. this could be kernel or systemd related -
this changed recently to newer version together with udev.
I had a case that cpu was always at max freq - I had to edit the cpufreq in 
cat /etc/default/cpufrequtils
GOVERNOR="ondemand"
MAX_SPEED="3.6GHz"
MIN_SPEED="1.4GHz"

hope it helps
