Bug Description
The update to linux-image 4.8.0-15-generic has caused both my laptop screen and external monitor screen to flicker at random intervals on my Skylake laptop, making the desktop annoyingly unusable at times. This issue is not present in the 4.7 or earlier kernels.
Upstream is aware of the issue: see https:/
