amdgpu.dpm=0 to shut off the Dynamic Power Management module, which contains AMD's powerplay, and everything works fine.

Upon further investigation, I would like to ammend my previous comment.

Setting amdgpu.dpm=0 will allow you to bypass those errors by disabling dpm 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=1

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, and in addition, the hwmon features actually showed up under /sys/class/drm/card0/device/hwmon/hwmon0/ and I can even echo speeds to pwm1.

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.

amdgpu.ppfeaturemask=1 add the GPU does not overheat.
