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.
