Renoir is a bit too new for us since the official drm version is 5.4, you currently have to build the 5.5-wip branch of drm-kmod for it to work. Also, I've fixed the framebuffer thing, you no longer have to disable it!! (Not everybody even had to ever do it. The issue was that we did not disable our simple framebuffer when the driver expected it (our Linux compat layer would only try to kill other Linux framebuffers) so our framebuffer would literally just overwrite device memory that the driver was using to initialize all the GPU firmware. On my Vega card, this would only happen at 1440p/4K. With smaller EFI framebuffer resolution, the memory would luckily not overlap :D)
