I believe that this backport is causing screen flickering problems on
Dell XPS13 9350, c.f. LP: #1554613 (where you'll find a bisect log
pointing to this backport, and dmesg msg on first error)

Title:
  Backport more recent driver for SKL, KBL and BXT graphics

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  We need to support Skylake (SKL), Kabylake (KBL) and Broxton (BXT)
  graphics in xenial, but the kernel driver is not fresh enough for
  proper support.

  For the kernel the plan is to provide a separate driver module
  (i915_bpo) like for Skylake/Broadwell/Braswell in vivid. The drm/i915
  driver in 4.4 is not recent enough for SKL/KBL/BXT, so pulling the
  driver from current drm-intel-next branch would provide what'll end up
  in 4.6. The i915 drivers will be modified so that only i915_bpo loads
  on SKL/KBL/BXT machines, and only there. The driver will get further
  updates along the way, and possibly also rebased to a later kernel
  release.
