How exactly can you see it? :) If you can see actual text on the screen after the loader and before=20 the driver is loaded, you haven't actually turned the efi framebuffer=20 off. Make sure you're actually booting with hw.syscons.disable=3D1 (garbage=20 should be on screen after the bootloader starts the kernel), disable=20 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. =
