Some other things that are really important and should be mentioned on the wiki: - radeonkms/amdgpu currently conflicts with the EFI framebuffer, have to use 'hw.syscons.disable=1' to disable it (and lose graphics output until the driver loads) as a workaround — https://github.com/FreeBSDDesktop/DEPRECATED-freebsd-base-graphics/issues/170 - amdgpu currently requires the following patch to unbreak OpenCL, Vulkan and Xwayland: https://github.com/FreeBSDDesktop/kms-drm/issues/33#issuecomment-422793245
