--- Comment #7 from Michael Long <harn-solo at gmx.de> ---
I tried several times to bisect this problem but it is an incredible task for
me. Between the bisection steps I had a variety of other hangs and freezes not
related to drm. 

In the meantime I've also tested 4.2 kernel extensively and so far the original
problem is gone. Occasionally (1 out of 20 resumes) instead of the KDE unlock
screen the last console output is shown but no traces of error messages or
backtraces. I leave it like that. Thx for your time anyway.
