Right now eEven 65536 interruptsINTR_IRQ_INVALID seems excessive. I suppose some futurelike rather a lot of interrupts right now.
I suppose some future device might need that many internally, but right now even 65536 exceeds
all real world devices. Additionally the resource manager code breaks
if you set the maximum to the maximum unsigned valuenow even INTR_IRQ_INVALID exceeds all real world devices.
