[drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3 log spam on 5.16.3

Brief summary of the problem:

I recently upgraded from Kernel 5.15.13-arch1-1 to Kernel 5.16.3-arch1-1, and since booting the log has continuously been spammed with the message [drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3.

As of this writing, this is the only symptom. I have display timeouts/locks/sleep disabled, and have not yet tried playing a demanding game to see if it hangs.

Issue did not exist on previous kernel
