Comme= nt # 35 on bug 10044= 3 from Devin Prince 
Upon further investigation, I would like to ammend my previous=
 comment.

Setting amdgpu.dpm=3D0 will allow you to bypass those errors by disabling d=
pm
altogether, but the consequence is that the fans will stop spinning almost
entirely (slow or no fan speeds when they should be ramping up).

Instead, set:

    amdgpu.ppfeaturemask=3D1

which enables the card to broadcast all of its power states properly. With =
this
enabled, all the errors mentioned in this thread vanished from my system, a=
nd
in addition, the hwmon features actually showed up under
/sys/class/drm/card0/device/hwmon/hwmon0/ and I can even echo speeds to pwm=
1.

I'm unsure if this has any adverse effects on anything, but if it does not,
perhaps ppfeaturemask should be set to default enabled in the amdgpu driver=
.
