relevant dmesg output

On an Alienware 15R3 with hybrid graphics (Intel/AMD RX470) I get the above error message (inter alia) in dmesg both during boot-up and whenever the dGPU gets woken from pm-suspend. This is not breaking, per se - the dGPU will perform it's duties normally when called upon, but takes a long time to 'go back to sleep' when no longer needed - see the bunch of

spam in dmesg. But maybe this has something to do with that?

dmesg attached.
