Other than the error message is there an actual problem?  Please file
a bug and include your dmesg output (with amdgpu.dc_log=1) and xorg
log (if using X) and describe what display connectors are expected.
Also, if this is a hybrid laptop with multiple GPUs what mode is it in
and is there a difference if switch to a different mode (e.g., hybrid
vs dGPU only).
