I was very confused by the separable quadratic extension example in my comment, but Wittenberg restricts to the geometrically integral case, so the example is not allowed (the OP did not have this condition). I had guessed that the perfect field business was just going to be deduced from the alg closed field case by descent but given that I couldn't understand the case of a quadratic extension I was hesitating to suggest this. For this sort of thing to work the assumptions must of course be invt under base change! | |
