well I dont know enough about how the electronics of all this is implemented, but if any of the power supply (like onboard SMPS regulators) is involved in the CPU voltage reduction of some of these C* states, I wouldnt be suprised that cranking up to full voltage does take some time, 'some' being rather long and rather indeterministic in the context of an RT application it is pure conjecture though anybody here who can comment on CPU voltage reduction and how that is done? that could also explain different board behavior - Michael > Eric > ------------------------------------------------------------------------------ > Free Next-Gen Firewall Hardware Offer > Buy your Sophos next-gen firewall before the end March 2013 > and get the hardware for free!
