Currently running amd-staging-drm-next 0313e8bfbbdd. The behaviour is now
improved, though is still regressed vs. mainline.
Unblanking works. If I allow the problem monitor to display “no signal”, it
becomes effectively disconnected, and becomes reconnected (as if physically
freshly connected) on unblanking.

Broken (same symptoms, though the kernel log looks a little different) with
drm-next-4.15-dc (fbf0c14dd75) (merged with 4.13.4).

Apparent EDID errors
HDMI monitor set to 1920×1080, but on unblanking gets set to 1152×864.
This is the second time that I've seen this. Both times it's happened on the
first unblanking after boot; both times, using drm-next-4.15-dc.

Bad EDID output (4.17-rc3 + DC)
Once this happens (after VESA blanking long enough for the problem monitor to
fully go to sleep), it persists until reboot.

I remember this having this issue and found that switching to the console
(CTRL-ALT-F1) and then back to X once or twice woke the monitor.

EDID problems are gone in drm-next-4.18. However, the disconnection issue
remains.
