have you tried other payloads? This might be a SeaBIOS issue and not a coreboot one.
No, I haven't tried other payloads like embedded grub, but it also doesn't reach coreboot boot menu (where I can run memtest for example). It seems that something broken in video adapter init (intel core graphics) because if I boot with external monitor detached then boot succeeded. Monitor detach after boot start doesn't solve the problem.
How to configure coreboot to boot debian 12 with non-seabios payload?
