Different GCC versions result in different machine code output. If the problem repeats appear/disappear with slightly different code placement, it is already broken. Just in case, I removed the output tree, and built v6.0-rc7 kernel from the clean tree. I swear to see the boot failure. I want to agree my patch is not the cause of the issue. -- Best Regards Masahiro Yamada
