If that turns out to be the bad commit, it doesn't really surprise me, and that in itself is depressing. It might be helpful if you could add drm.debug=14 module parameter, and provide dmesgs from boot both with and without the above commit (it's enough to see i915 load). Please also provide /sys/kernel/debug/dri/0/i915_opregion.
