Michal, this issue is on KBL whereas original issue is on CFL. Likely this
could be a different issue. Can you please reproduce this issue with drmtip
(https://cgit.freedesktop.org/drm-tip)? 
Please report a new issue if seen on drmtip.

@Tom, are you still able to reproduce the issue with some information in crash
dump file? I would recommend to verify the issue with drmtip.
