I had left the system idle for some time and came bake to wake it up.
The screens never turned on though.
There should be plenty of details in the log but a quick summary:
Radeon Fury, Ubuntu 18.04, dual 4K displays: Dell P2415Q, Samsung U24E850

Kernel is drm-next-4.17 @ cc9e992dfb5bb48f59f3fbc1268d3f38d2c86ef3
