Title: pstate_idle is broken on 4.1, high fan speed when idle Status in linux package in Ubuntu: Triaged Bug description: The system has high fan speed even when idle. Overall, the fan never gets to a fan speed as low as with the 3.13 kernel. When running the kernel with intel_pstate=disable, i get much more governor choices, and when selecting "powersave" with this, i get much better behavior, just as with the 3.13 kernel.
