That's because it repeatedly fires without a proper handler, and only appears then. > Are you seeing this with all the ethernet updates for the APQ8060 in > Linus' branch?

(mostly) stock v4.8-rc1 exhibits the same issue, and your fix doesn't help this particular issue. Reverting your fix *and* applying the above revert makes it work again. Which is just papering over the issue, as it only does something when the interrupt is seen for a second time. I must be missing something obvious... M. -- Jazz is not dead. It just smells funny...
