 this reminds me of a problem i have on an asrock board.  A520M/ac
 with a ryzen 5600G cpu installed.  trying to bios boot fails with
 the hex addresses like you describe (they're memory ranges, you
 can find the code in the x86 efiboot.)
 
 when "CSM" is enabled in the bios, it seems to still load the
 efiboot program instead, perhaps expecting it to work in bios
 mode.  i was unable to boot in BIOS mode while there was a
 visible EFI boot program -- removing the efi/boot/bootx64.efi
 (in what ever path) made it actually load the BIOS booter.
 
 this ended up avoiding an older uefi vs radeondrm issue that
 should be solved now, so i should be able to uefi boot now.
 
 anyway, the hex spew indicates that efiboot i starting up but
 it is not getting far enough to boot or ask question.
