I should have had a look at my inbox, would have save me a log of work
bisecting. Yet i come to the same conclusion:
# first bad commit: [e98c58e55f68f8785aebfab1f8c9a03d8de0afe1] Merge tag
'drm-misc-next-2017-05-16' of git://anongit.freedesktop.org/git/drm-misc
into drm-next
I suspect it is some vblank change as it shows up in every trace i have
seen while bisecting, but that is just a wild guess...
Greetings,
Tobias
