Title:
  Lenovo Y700-17ISK: can't claim BAR 6: no compatible bridge window

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Lenovo Y700-17ISK (Intel Core i7-6700HQ/RAM 16GB/SSD 512GB/Nvidia GTX960M 4GB)
  Operating system: Ubuntu 16.04 (xenial-desktop-amd64.iso 04-Mar-2016, kernel 4.4.0-10-generic, nvidia 361.28)

  After installing Xenial, I installed all available updates too, and
  then I examined detally dmesg output in order to see if everything is
  ok between Ubuntu and my new notebook:

  [    0.357806] pci 0000:01:00.0: can't claim BAR 6 [mem 0xfff80000-0xffffffff pref]: no compatible bridge window
  [    0.357830] pci 0000:01:00.0: BAR 6: no space for [mem size 0x00080000 pref]
  [    0.357831] pci 0000:01:00.0: BAR 6: failed to assign [mem size 0x00080000 pref]

  I'm not an expert so I'm not sure about all (potential) consequences
  of this problem, but I think that this problematic lines shouldn't
  exist inside my dmesg output.

  When compared to other two Asus notebooks (both with Xenial installed
  on ssd), my new Lenovo boots up much slower due to some other issues
  too:
