    Hmm. It seems the c3 compensation is triggering when it shouldn't, or
    maybe its over compensating.

    I can't reproduce it on my laptop. Do you recall if in previous tests
    you saw anything like this? I'm trying to narrow down if its just a
    difference in hardware or if something in the c3 idle code changed.

    thanks
