I've been using a couple of ryzen laptops (an HP with a 2500u, then an HP with a 3700u) for about 5 years.
It works pretty well, except:
When the laptop wakes up there's a good chance that the UI shows up but I can't click on anything or type.
I can then reboot by holding Alt-SysReq and typing REISUB.
Or: The screen is still black, and nothing works, as above.
I can run games, though if I play something like GTA-V, it will eventually get too hot and I have to hard reset.
This is because the fan control doesn't properly work.
