Title:
  Booting with Nvidia GTX 970 hangs with an orange screen in kernels 4.7
  and 4.8rc1 (but works with 4.4.0)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Booting with Nvidia GTX 970 hangs with an orange screen in kernels 4.7
  and 4.8rc1 (but works with 4.4.0).

  I've tried:
    * Plain yakkety 4.4.0-34-generic
    * Mainline kernel 4.7
    * Mainline kernel 4.8rc1
  and only the first one works. Kernels 4.7 and 4.8rc1 freeze with a bright 
orange screen.

  Best I can tell, the frozen orange screen coincides with kernel log
