[Kernel-packages] [Bug 1351014] Re: Extessive timeout warning on some machines with i915_bdw
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- trusty' to 'verification-done-trusty'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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.
