The thermal control runs every second and sleeps with "interruptible"...
so it should not have such a laod average imho :) Now it's possible that
what it does during that "second" is long enough to end up not sleeping
that much (though it's also sleeping while doing i2c accesses, but that
is uninterruptible for obvious reasons at the i2c driver level).
