--- Comment #19 from Denis <denys.kostin at globallogic.com> ---
Hi Georg, as Danylo mentioned, we couldn't reproduce this problem, so the only
way I see now - to try and bisect the kernel.

It might be hard because of some patches, required for building some
intermittent versions, but in my experience - it is possible to google/find
these patches and apply them.

There are two sources of kernels can be checked:

https://github.com/freedesktop/drm-intel
https://github.com/freedesktop/drm-tip

First one should be stable, second - the most up to date (for your case I would
suggest stable, because, according to you, failure appeared somewhere in 4.9
version)

How-to instructions:

https://git-scm.com/docs/git-bisect
https://01.org/linuxgraphics/documentation/build-guide-0

Good luck.
