Public bug reported:

I performed an update of Ubuntu 16.04 LTS by using "sudo apt-get
upgrade". One of the packages that were updated was "ubuntu-drivers-
common", and it was updated from version 1:0.4.17 to 1:0.4.17.2 (note
that my system never had version 1:0.4.17.1).

After the next reboot my laptop's system fan went constantly on maximum
speed, even if the CPU was nearly idle (according to the System Monitor
in Ubuntu) and there were no heavy system load.

The only thing I did to remedy this problem was to downgrade ubuntu-
drivers-common to 1:0.4.17 (pay attention to the version number; I did
NOT downgrade to 1:0.4.17.1 because the latter version doesn't exist in
Ubuntu's default repositories). After the next reboot the problem was
gone and the laptop's system fan functioned as normally.

So it's evident that either 1:0.4.17.1 or 1:0.4.17.2 or both (by a short
chain of changes) introduced this problem.
