Not sure, one possible cause is that cpuidle code is calling pwrdm_set_next_pwrst(), I recall having some issues if I tried calling this function within idle loop. Rest of the PM code is calling set_pwrdm_state().

I haven't really tried cpuidle too much, I just wanted to get suspend + dynamic idle work as the code in those is simpler => easier to get chip off state to work.
