Title:
  [Haswell i915] WARNING: CPU 0: at ... i915 intel_ddi.c
  intel_ddi_pll_mode_set

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I get this whenever I resume from hibernation. When googling for
  "WARNING intel_ddi_pll_mode_set" there are countless other bug reports
  of this sort for other projects (Redhat, ChromeOS, ...), so this seems
  to be a popular Haswell issue.
