Now I tried out loops at many places and have gotten up to line 340 in arch/x86/kernel/head_64.S System reboots within the following assembler instructions (does not reach line 359). So efi_main() returns successfully but the assembler code following it gets something wrong. I'm going to try further to determine which line between 340 and 359 is the "bad" one.
