--- Comment #35 from Jari Tahvanainen <jari.tahvanainen at intel.com> ---
Juridan - let's start to work on this. Sorry about this delay again.

As a first step please provide full dmesg from the boot to the problem.
To obtain a dmesg with debug information, add drm.debug=0xe to your kernel
command line (on grub assumable on your case). Attach the log here "add an
attachment" ...
See instructions on https://01.org/linuxgraphics/documentation/how-report-bugs 

After dmesg then try to reproduce the problem with the latest kernel from
drm-tip. See build guide
https://01.org/linuxgraphics/documentation/build-guide-0 for instructions how
to get and compile drm-tip.
