While booting coreboot 4.17 to SeaBIOS 1.16 on a Supermicro X9SAE-V, the keyboard flashes on then off (LED Backlit USB keyboard) and does not let me interact with SeaBIOS until the linux kernel is loaded on the OS side. Currently using a PS/2 keyboard to unlock my boot drive via SeaBIOS. Using any other GPU does not affect the USB keyboard and works just fine. The Radeon RX 6800XT is a reference card with a USB-C port on it, naturally I tried a USB-C adaptor on the GPU to get the USB keyboard to work, but no luck. Building coreboot with either native, secure VGABIOS loading, or libgfxinit does not fix the problem either. Seems to be specific to this GPU on hardware init. Coreboot dot config is attached.

sure sounds to me like the USB-C port on the card is causing SeaBIOS' USB init to fail. I'm guessing nothing at all to do with coreboot. Raise the SeaBIOS logging level to 3 and grab a cbmem log after booting
