@P.D.: I also have the eighth (and final) kernel almost ready for you. It is based on commit:
325f8e18c8ac drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5 and it should be available at: https://kernel.ubuntu.com/~kmously/1813657/kernel-kmously-325f8e1-2dRL in about 40 minutes. This should be the last kernel that you'll need to test for bisection. I think the problematic change is "drm/i915/execlists: Force write serialisation into context image vs execution". This can be confirmed by confirming that the eighth kernel (which does not have that change) boots fine.
