If core is dead then it can not assert interrupt, it's more possible
No, but it may have asserted the interrupt and then died.
that it's spurious interrupt or interrupt from other device (IRQ is shared) and nothing should be handled. In this case reply by IRQ_HANDLED is incorrect because nothing is handled.
In this case we cannot be sure if it was our interrupt. IRQ_NONE however means that we are sure. Likelihood is not a relevant question here. We must know for sure if we claim IRQ_NONE, because IRQ_NONE has consequences. Regards Oliver
