    The ondemand governor seems to be singled out not because it has unique
    problems, but because it seems to be used by Fedora Core for some strange
    reason.

    I would judge that any bugs in cpufreq_ondemand.c are likely equally
    evident in cpufreq_conservative.c, for example. I think the two have the
    same background, and seem to have the same broken locking.

    See above. I seriously doubt this is ondemand-specific. The whole cpufreq
    locking seems to be very screwed up.

    The current -git tree will complain about some of the more obvious
    problems. If you see a "Lukewarm IQ" message, it's a sign of somebody
    re-taking a cpu lock that is already held.
