relevant dmesg output

After rebuilding the mainline kernel from git today in order to see if the
recent change: "PCI: Reprogram bridge prefetch registers on resume" would help
with my crash issues. It does seem to do this, however I noticed that my dGPU
would now no longer properly power down. dmesg give me this:

amdgpu: [powerplay] Failed to retrieve minimum clocks.
amdgpu: [powerplay] Error in phm_get_clock_info 

This error did not occur on previous kernel versions.
