Somebody in the thread at some point said:

| -               set_irq_handler(irqno, handle_edge_irq);
| +               //set_irq_handler(irqno, handle_edge_irq);
| +               set_irq_handler(irqno, handle_level_irq);

|    When the system resumed, it is looped in handling low level IRQ,
| which is what I mentioned before, "the IRQ strom".
|    Any thoughts?

Normally I would say we just need to take your patches and move on even
if they were on our local tree only, since it solves a problem.

But if I understood it they only solve this storm issue specifically
around the wake action... I am not sure at all that the stuff we see
around level IRQ (also it seems to stun the device sometimes through
motion sensors level on stable branch) is not a general problem some or
all of the time outside of wake too.

It feels like we have all this time (I saw this storm behaviour using
level back in early part of the year) either been missing a trick
somewhere about using level or it's broken somehow.
