Working AMD VEGA 56 based graphics card

[Andreas Drewke]

Hi,

I had a first kind of error. In console where I started X I get the 
following message in a endless loop: "amdgpu: The CS has been cancelled 
because the context is lost.". This would leave X11 in a unusable 
state(no HID input, no graphics output). Killing X11 and restarting works.

Many thanx and

Best regards
Andreas
