dmesg output showing the drm error

I continue to have this problem. The system is an HP 17-g121wm with a A10-8700P
processor. This system contains an AMD Radeon R6 gpu.

I am testing Fedora 28 running the Linux 4.17 kernel.

This error leaves causes my window system to crash, sometimes rotate its
orientation in the wrong way, and leaves a black screen.

I understand there has been some progress on this. It would be really helpful
to get this fixed.
