Title:
erratic fan speed and little control kernel 4.2
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan
started speeding and slowing without good reason even when the PC is
idle.
I tried various things but then found that if I leave the computer off
for a long time and let everything cool down then when I boot from
cold the CPU fan is stable.
To test my theory of cold start out I then ran
sudo cpupower frequency-set -g powersave
followed by
sudo cpupower frequency-set -g ondemand
The final mode is the initial mode. Almost immediately as soon as I
moved to powersave mode the erratic fan speed started. It did not
stop when I returned to ondemand.
Temp fix for this behaviour is - go and have a cup of coffee and let
the computer cool down when you restart: shutdown then start from
cold.

CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1.20 GHz - 2.80 GHz
available frequency steps: 2.80 GHz, 2.80 GHz, 2.67 GHz, 2.53 GHz, 2.40 GHz, 2.27 GHz, 2.13 GHz, 2.00 GHz, 1.87 GHz, 1.73 GHz, 1.60 GHz, 1.47 GHz, 1.33 GHz, 1.20 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1.20 GHz and 2.80 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz.
