I posted about this problem perhaps a year ago - when running with AMDGPU, my system won't turn off, I have to hold the power button down for a long time, forcing it down.
At that time, various people commented. but AMDGPU didn't work at all for me in the end, didn't talk to my HDMI display. I gave up on it. Thanks to all the great help here, I finally got my system properly updated and AMDGPU working, and it finally talks to my HDMI display. But, it still doesn't shut down. Is it a bug? Is my system still not right? Is there something I have to do yet?
