--- Comment #14 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
[   26.597300] [drm:intel_ddi_pll_init] CDCLK running at 450000KHz
  3840x2160 (0x46) 533.250MHz +HSync -VSync *current +preferred

533 > 450, so this is never going to work. So like bug 85621, we're going to
need to grow these max cdclk checks and filter out such modes.
