I have a device that supports MSI and INTX-disable, and, with MSI on (and delivering interrupts successfully) also sends legacy interrupts (on the IRQ that is no longer associated with the device) unless INTX is disabled. Without the intx_disable(), the kernel disables the IRQ entirely and breaks a random other device in my system.


That sort of behavior is an example of why I wrote pci_intx() in the first place, and employed it by default throughout the ATA drivers (before it migrated into PCI core).
