    I've seen the bug report. init_workqueues comes after smp_init.
    The idea I'm currently playing with is a simple check in the tsc
    code if the tsc clocksource is already registered or not.
    When smp_init is called the tsc is not yet registered, we could
    just set the rating to zero.
