PS1, Line 11: Unfortunately this gcc 11.2 is causing problems for some boards:
            : in example, AMD Lenovo G505S can't boot to Linux.

I'm using a SeaBIOS master. As for "payload problem or a coreboot problem" - after lots of testing, I am sure that something compiles badly with a new gcc, but don't know if it's in a coreboot or SeaBIOS; if that could help, I may try building a mixed "coreboot with old gcc, SeaBIOS with new gcc"

Will reply if I could get this output. Although, my first idea is to compare the compiler flags of gcc 8.3.0 vs 11.2 (i.e. if some flag got added and has an unpleasant default), or if some workaround patch = which has been dropped during a gcc upgrade - is still needed and should be rebased).
