I'm on mainline, I can reproduce the do_IRQ: no irq handler for vector 4.33 during a
normal suspend/resume cycle, but afaict dead irqs only showed up on hibernation fail. Not all
platforms supported on i915 seem affected, though I've sometimes also seen it affect
other drivers.. MEI iirc
Previous attempt with single s/r:
