Title:
  Using eDP leaves kernel log with "Timed out waiting for DP idle
  patterns" messages

Status in HWE Next Project:
  Fix Released
Status in The Linux Kernel:
  Fix Released
Status in “linux” package in Ubuntu:

Status in “linux” source package in Quantal:

Bug description:
  [Impact]

   * This confuses end users. They think that this is a relevant message instead of an
     unimportant accident to the eDP

  [Test Case]

   * Use an eDP haswell system
   * See this message in dmesg

  [Regression Potential]

   * Low. This patch just skips a port check on eDP machines
   * It has already been tested on eDP machines

  [Other Info]

   * private bug 1097143

  [Original message]

  eDP on haswell graphics puts some stuff in dmsg that is scary to
  users. Worse, these messages are displayed on suspend/resume, and
  because we don't have vt-switchless resume support in ubuntu yet, when
  the graphics don't work it seems like these messages are the culprit.

  Dmesg:
  [11577.928164] [drm:intel_dp_set_link_train] *ERROR* Timed out waiting for DP idle patterns
  [11577.928167] [drm:i915_write32] *ERROR* Unknown unclaimed register before writing to 64040
