<pre>So I stripped this down, and the ring error pops up after I've applied a new
pp_table and start utilizing the GPU.
My guess is this error has something to do with why this doesnt work in
drm-next-4.19-wip
[ 2.635258] amdgpu: [powerplay] Failed to retrieve minimum clocks.
[ 2.635259] amdgpu: [powerplay] Error in phm_get_clock_info
That error is not present when I load 4.17.0-rc2-180424-fkxamd kernel.
I apply same pp_table file while running 4.17.0-rc2-180424-fkxamd, and it works
as expected.
So there is something funky in the powerplay of drm-next-4.19-wip</pre>
