--- Comment #2 from Daniel Vetter <daniel at ffwll.ch> ---
Is this readily reproducible or just a freak hang?

If you can reproduce it it'll be interesting to figure out when this happens.
Most likely we have a stray MMIO write somewhere that completes the flip too
early. Otoh how that manged to kill ivb is beyond me, the scratch page ptes
should saves us.
