<pre>I think it is a regression, I always used hibernation with 4.11.0. Since 4.12.x
starts this resume problem.
I done test with drm.debug=0xe:
first time, I executed "systemctl hibernate" and at kernel time [53.314063]
resume fails, system is working but screen is off;
second time, I executed "systemctl hibernate" and at kernel time [431.539799]
resume fails too. This time, system is always working but screen is on with
dirty image, no ctrl-alt-f1 possible;
in attach dmesg.
Thanks
P.S. I changed hardware for do better test.</pre>
