Hello Joseph,
I cannot test the issue as I do not have the laptop any more but
unfortunately the issue persits on my new laptop (Dell Latitude E5470):
the working version is 4.4.0-59.80 but with 4.4.0-62.83 and next the
problem comes back. I will post a separate bug for it.

Daro, the next step is to fully commit bisect from kernel 4.4.0-45.66 to
4.4.0-47.68 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following
Tested on 4.10.0-041000rc1-generic #201612252031. The problem persists.

Daro, thank you for reporting this and helping make Ubuntu better.
In order to allow additional upstream developers to examine the issue, at your
earliest convenience, could you please test the latest upstream kernel
available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please
