When any slot IRQ becomes disabled we mask the CA1 + * umbrella interrupt. Only when all slot IRQs become enabled do we unmask + * the CA1 interrupt. It must remain enabled even when cards have no interrupt + * handler registered. Drivers must therefore disable a slot interrupt at the + * device before they call free_irq (like shared and autovector interrupts). + * + * There is also a related problem when MacOS is used to boot Linux.
