Strange. If I didn't keep an older amd-staging-drm-next kernel from October
2017 in use where S3 resumes work every time, I would doubt my hardware - but
the way it is the only possible cause is a kernel change sine then.

Sure, will attach my .config (as used with the current drm-next-4.17-wip) after
this comment.

Tested with today's drm-next-4.17-wip git: With "amdgpu.dc=0" on the kernel
command line, resume from S3 works fine for me, both from the console (before
starting X11) and when running X11.
(But of course, no 4k/60Hz video and no HDMI audio with amdgpu.dc=0, so that is
not really an option for actual use.)

So the resume-from-S3 failures are definitely caused by something in the DC
code that changed since early October 2017.
