            Bug ID: 97548
           Summary: DPM states not working
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu-pro
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: jarkko_korpi at hotmail.com

I am using 4.6-staging because I need the audio driver it provides.

I have been trying to lower the voltages of the card by bios editing and there
seems to be no issues with windows, but I dont seem to get higher DPM states in
use at linux. Something is broken.


dmesg is spammed with these

amdgpu-pro, mint 18, rx480. Latest 4.6 kernel from git (agd5f/linux).
