--- Comment #10 from Edward Kigwana <edwardwwgk at gmail.com> ---
Not sure what commit fixed it for me but with amd-staging-drm-next
525b7b1e13c3214f04c9ab4d72c88f55a7bd4288 I no longer have this issue.


[    2.285918] [drm] initializing kernel modesetting (POLARIS12 0x1002:0x699F
0x1462:0x8A90 0xC7).
[    2.285925] [drm] register mmio base: 0xDF300000
[    2.285925] [drm] register mmio size: 262144
[    2.285929] [drm] probing gen 2 caps for device 8086:1901 = 261ad03/e
[    2.285930] [drm] probing mlw for device 8086:1901 = 261ad03
[    2.285931] [drm] add ip block number 0 <vi_common>
[    2.285932] [drm] add ip block number 1 <gmc_v8_0>
[    2.285933] [drm] add ip block number 2 <tonga_ih>
[    2.285933] [drm] add ip block number 3 <powerplay>
[    2.285934] [drm] add ip block number 4 <dce_v11_0>
[    2.285935] [drm] add ip block number 5 <gfx_v8_0>
[    2.285935] [drm] add ip block number 6 <sdma_v3_0>
[    2.285936] [drm] add ip block number 7 <uvd_v6_0>
[    2.285936] [drm] add ip block number 8 <vce_v3_0>
[    2.285942] [drm] UVD is enabled in VM mode
[    2.285943] [drm] UVD ENC is enabled in VM mode
[    2.285944] [drm] VCE enabled in VM mode
...

As before enabling dpm results in an instant lockup that I can't even begin to
debug since the kernel locks up and I don't have a serial console.
