We have documented case of very bad performance issue on rt2800pci device, because it generate spurious interrupt, what cause irq line is disabled: https://bugzilla.redhat.com/show_bug.cgi?id=658451 We already address that problem in separate patch by returning IRQ_HANDLED from interrupt handler. We think similar fix is needed for other rt2x00 PCI devices, because users report performance problems on these devices too.
