    Right, this is why we're using the native variants in the early loader.
    So we need a different method for detecting very early whether we're
    running as a guest.

    What I'd like more, though, is if we continue debugging the original
    issue where we fail in load_ucode_intel_ap(). Does it happen on this line:

    initrd_start_addr = (unsigned long)__pa_nodebug(*initrd_start_p);

    where we deref the initrd_start_p? Do you have a full splat with a Code:
    section?

    Thanks.
