This text is flush with the left edge of the screen, and looks 'normal' - like it did before I added 'hw.syscons.disable=1' to /boot/loader.conf. 2: After about 3/4 of a screen height of text (where height is unknown, but not an 80x24 old-skool thing, and not as-tiny-as-possible-on-a-4k-monitor either, but readable) no more text appears. 3: Within a small (10pixel or so) bar at the top of the screen, weird coloured patterns appear in various shades. This lasts several seconds. 4: As the 'amdgpu' driver loads, I get a terminal again, but this time it looks a bit unusual - maybe the font's a bit different, and definitely there are large margins on the left and right sides of the screen. How does what you see relate to this? The thing that happens at [2] above is evidence that the 'hw.syscons.disable' is working. Do you get that? If not, one suggestion I'd have is to open /boot/loader.conf and retype the line (not copy/paste) - on rare occasions I've had this work because there was some unnoticed unicode character in place of one of the ascii chars. > > > So: is it a lack of Vega 8 firmware? > > > > raven is raven, there's no 'vega8' firmware AFAIK. > > I looked around and that does seem to be the case. > My understanding is that vega8 is the Ryzen 3 equivalent of vega11 in Ryzen 5. I've seen something (don't remember where) that suggested the number (8 or 11) was simply how many triangle-drawing units there were. I can't confirm that though.
