--- Comment #8 from Luke McKee <hojuruku at gmail.com> ---
I commented because the user here had the error relating to powerplay failing
that I have seen in other threads.

https://forum-en.msi.com/index.php?topic=298468.0

[46667.236028] kernel: amdgpu: [powerplay] 
                        failed to send message 309 ret is 254 
[46667.236041] kernel: amdgpu: [powerplay] 
                        failed to send pre message 14e ret is 254 

Thought this issue might be related to the motherboard bios not properly
setting up MMIO BARs.

I'll open a seperate ticket i a week if the Polaris 11 support is still broken
after your next push to linux 4.16. I'm sure you at AMD would be aware of it.
