HAVEGE might conceivably produce genuine randomness if it could run on an asychronous cpu (http://en.wikipedia.org/wiki/Asynchronous_circuit#Asynchr...). Otherwise, no. It's just a baroque way to collect randomness from elsewhere - if that.

Well, thank you Captain Obvious.

The question is not about source of randomness (contemporary CPUs are not asyncronous, but contemporary PCs as whole most certainly are asyncronous: memory access is just an obvious example), the question is how much if it is actually retained in the output, if any.

You've managed to be both rude and incorrect. Next time think before commenting.

"Captain Obvious" is really funny though, I shall endeavor to use it more whilst conversing with minions!
