dmesg

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

My screens always act a bit weird when waking up, they often blink very many times and jump around a bit and give warnings in the logs etc. The Windows driver also shows warnings every now and then, FYI.
