Same issues here, the KP shows a thing with CPU "X" Caller, We doing something wrong? (the "X" is usually no.2 4 or 5 for me.) I'm using a Dell Latitude E6420 with an Intel Core i7 2670QM, 2x4GB Ram 1600MHz, 1600x900 screen and a 256GB SSD. Once booted everything works fine.
Also I seem to have USB problems when I boot directly from SSD, when I boot using the Install USB everything works as it should.
