    BenH advised to boot with udbg-immortal and out came:
    (watch it at very slow speed, as it's only 3sec long)

    I've enabled[0] FB_NVIDIA and during normal booting the screen flickers
    after the "... : fixmap" message and the screen clears and is filled again
    from the top - maybe the messages would've been there if booted w/o the
    framebuffer enabled.

    Right now I'm happy that Ben's fix helped to get past this message, but
    the system remains unsuable[1] with the latest -git, but more debugging
    has to wait until tomorrow...
