Title:
  Extessive timeout warning on some machines with i915_bdw

Status in HWE Next Project:
  New
Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Released

Bug description:
  SRU Justification:

  Impact: Kernel warning every boot making it seem like the system is faulty but it is harmless. This only applies to i915_bdw on trusty, and is impacting certification on some prerelease machines.
  Fix: Upstream increased the timeout required to hit it so it will not affect the machines we have anymore in 3.14, and also demoted it from a warning to DRM_INFO_ONCE.
  Testcase: Boot trusty on an affected broadwell machine, check dmesg for warning

  [Results]
  Expected: There should be no WARNING messages for i915_bdw.
  Actual: This warning is displayed
