Bug Description
i915_bdw driver module in the trusty kernel is currently based on v3.14+backports, but it has turned out to be insufficient on real systems causing system freezes and/or GPU hangs with certain workloads. Some issues have been worked around but they trigger other bugs, and backporting bisected fixes dind't fix them on this branch.
Rebasing the driver to the latest tag from i915 upstream that doesn't include changes to core drm, plus additional fixes, should provide a better driver for the initial broadwell enablement.
