Title:
erratic fan speed and little control kernel 4.2
Status in linux package in Ubuntu:
Confirmed
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.

$ cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
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.
cpufreq stats: 2.80 GHz:11.93%, 2.80 GHz:0.00%, 2.67 GHz:0.40%, 2.53 GHz:0.44%, 2.40 GHz:0.51%, 2.27 GHz:0.55%, 2.13 GHz:0.35%, 2.00 GHz:0.72%, 1.87 GHz:0.84%, 1.73 GHz:1.00%, 1.60 GHz:2.16%, 1.47 GHz:4.61%, 1.33 GHz:16.83%, 1.20 GHz:59.65% (29241)

Tried intel_pstate but it is not supported for some reason on my
machine ie the following does not work and I am left with driver:
