Hey,
with the recent 4.19.x series of kernels I'm seeing several errors being logged
during boot for my R9 290 (HAWAII PRO) GPU:
> [   50.057264] amdgpu: [powerplay] Failed to retrieve minimum clocks.
> [   50.057266] amdgpu: [powerplay] Error in phm_get_clock_info

Since the system is coming up and accelerations seems to be working, this can't
be critical. Or is there something I need to set on the kernel command line (so
far I have: modprobe.blacklist=radeon radeon.cik_support=0 amdgpu.cik_support=1
amdgpu.dc=1)? Anyway, I thought I let you know. If you need more information,
feel free to ask.

Cheers,
Kai
