Comme= nt # 21 on bug 10809= 6 from Andrey Grodzovsky 
Please load the driver in debug mode so I can see the error co=
de value in dmesg
-=20
when loading the kernel add drm.debug=3D0xff

Also to trace where exactly the error originated from please install trace-=
cmd
and beore starting X (assuming you get the failure and the dmesg error righ=
t on
start)
sudo trace-cmd start -p function_graph -l amdgpu_cs_ioctl
and get the output from /sys/kernel/debug/tracing/trace
