Sierra install hanging

Maybe you guys can help.

Been running my X79-UD5 very happily on 10.10.5. But the itch to upgrade is getting me.

I am brand new to clover but I am running 2.3k rev 3766

I am hanging here and can't get past it

Appleusbxhci

Not sure how to bypass it or what I need to do to resolve it.

My bootflags are
Dart=0
Nv_disable=1
Npci=0x3000
-v
-f
CPUs=1



Thanks
