You mean that the latest stable 4.8.6 kernel already has these fixes or that
they will be included in 4.8.7?

Because if they are included in 4.8.6 they don't fix the problem, I'm still
seeing "[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A
FIFO underrun" quite frequently with the accompanying screen flicker.
