It's "fix commited", not "fix released" for 14.04. At the moment the new sysvinit packages are still in trusty -proposed (2.88dsf-41ubuntu6.1

Since this driver is meant to be used for power saving, it seems wrong to leave the system in the kernel default configured "performance" governor after boot, so I think it is pertinent to set this to "powersave" if it is the only suitable non-power hungry governor available. How to reproduce: 1. enable the intel_pstate driver on a recent Intel machine (Sandybridge or above) edit /etc/default/grub, modify the following: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=enable" and run: sudo update-grub and reboot. 2. login 3. wait at least 60 seconds for /etc/init.d/ondemand to complete check out the default cpufreq governor, you will see it is still set to the boot default of "performance": cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor With the attached fix the system will boot into a less aggressive cpufreq governor.
