installed el capitan on ga-x79s-up5-wifi with 3930k, getting appleusbxhci panic

hey everyone,

i just installed el capitan following rampagedev's guide. however, when i enable usb 3 controllers on my board (fresco logic and VIA), i get a panic from appleusbxhci when booting to the OS. all other devices seems to work ok except USB3. what would you advise?
