Hi Linus, Sorry for the constant spam on this..

(Usually some registers need to > be written with zeroes.) Changing the handler to handle_edge_irq() on the gpio side resolves the issue and gpiomon registers edges from the gpio like it should. So I think it's an ordering thing. Something like the gpio side sets the handler to handle_bad_irq() after the irqchip side sets it to handle_edge_irq(). Thanks for the help. Cheers, Daniel
