It might be related to this:

[=C2=A0 =C2=A010.482772] radeon: No coherent DMA available.


I updated my device-tree to add incoming pcie ranges, and that removes this error:

[=C2=A0 =C2=A010.161044] [drm] radeon kernel modesetting e= nabled.
[=C2=A0 =C2=A010.165168] [drm] initializing kernel modeset= ting (VERDE 0x1002:0x6822 0x1002:0x031E).
[=C2=A0 =C2=A010.171799] radeon: No coherent DMA available= .

 Well that reads like the problem is still there and yes when you don't have coherent DMA possibility that would explain why it doesn't work.

Can you provide us with a dump of /proc/iomem as well?

Sure:
