Oops! My apologies.
What distro?
Maybe a kernel setting, but it has nothing to do with rt patched 3.14
kernels per se. Is any governor enabled?
[rocketmouse@archlinux ~]$ zgrep CONFIG_CPU_FREQ_GOV /proc/config.gz

What always works is to check and change it
without a tool.
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
That always was quickly busted, as this path does not exist on my
machine. No cpufreq directory under any of the cpu* dirs. Maybe a
kernel setting? I'm on a 3.14-12-rt9 kernel
