--- Comment #211 from Filip Brygidyn <brygidyn.filip+freedesktop at gmail.com> ---
Thank you for fixing this, I wanted to report that in my case enabling DC does
not seem to cause any issues.
I am running amdgpu (no 'amdgpu pro' drivers on top) with following params:
"amdgpu.cik_support=1 amdgpu.modeset=1 amdgpu.dc=1 amdgpu.dpm=1"

Kernel version: 4.17.14 (arch)
GPU: MSI R9 390 Gaming 8G

Anyone knows which patches fixed this?
Link to a mailing list patch-set or a git hash on the mainline branch would be
much appreciated.
