Welcome to new Intel HW :-P So did you reboot into the new kernel from the old, maybe try reproducing but booting an old kernel and booting into the new one from it, it might be some hw state getting left set across soft reset or something, I'm hoping Intel guys pipe up on the other HSW issues, I only have one HSW laptop with an eDP panel and no external outputs on the Intel GPU.
