Upgrading to xorg-server 1.20 with xf86-video-amdgpu-18.0.1-2 and Mesa 18.0.4-1 results in failure to init monitors on secondary GPU Radeon 6850 in PCI 2:00:0

Downgrading to 1.19.6 with xf86-video-amdgpu-18.0.1-1 fixes issue and I can then use xrandr to init those monitors again.
No specific xorg config files.
