Bug#921114: AMD Radeon RX 580: no GL display, "amdgpu: The CS has been cancelled because the context is lost"

[at46]

I cannot confirm this bug with an AMD Radeon RX 570 4gb. There are no 
problems with firmware-nonfree/20190114-1 and launching opengl games. 
The problem seems to be more hardware specific or is caused by something 
else.
