I have #RUNTIME_PM_DRIVER_BLACKLIST="amdgpu mei_me nouveau nvidia pcieport radeon" sauron:~$ lspci |grep -i nvidia 01:00.0 VGA compatible controller: NVIDIA Corporation TU104GLM [Quadro RTX 4000 Mobile / Max-Q] (rev a1) 01:00.1 Audio device: NVIDIA Corporation TU104 HD Audio Controller (rev a1) 01:00.2 USB controller: NVIDIA Corporation TU104 USB 3.1 Host Controller (rev a1) 01:00.3 Serial bus controller [0c80]: NVIDIA Corporation TU104 USB Type-C UCSI Controller (rev a1) So you're saying that I need to blacklist 01:00.1 and without that it hangs when suspending the powered off nvidia chip, which is what I'm experiencing as a hang when I unplug power?
