dmesg with cik_support=1 dc=1
When using kernel 4.16.0 and amdgpu with cik_support=1 dc=1 on Kabini (A4-1200) the screen will become blank once the module is loaded.
dmesg has the following error:
[drm] Cannot find any crtc or sizes
With radeon or amdgpu.dc=0 the screen lights up, but I cannot use amdgpu for daily work due to bug 101926.
