    It hangs solig during boot (after starting kjournald) on Asus L5D (non-SMP x86-64),
    which is caused by this patch:

    8250-serial-console-locking-bug-spelling-fix.patch

    (from binary search).

    If this patch is reverted, it oopses like in the following trace.

    At the same time it works fine on an SMP box (dual-core Athlon 64).

    Greetings,
    Rafael
