How exactly can you see it? :) If you can see actual text on the screen after the loader and before the driver is loaded, you haven't actually turned the efi framebuffer off. Make sure you're actually booting with hw.syscons.disable=1 (garbage should be on screen after the bootloader starts the kernel), disable the amdgpu auto loading and try loading it manually over SSH. > So: is it a lack of Vega 8 firmware? raven is raven, there's no 'vega8' firmware AFAIK.
