Modified Files: src/sys/dev/pci: virtio_pci.c Log Message: Ensure MSI-X is disabled if allocation of MSI-X interrupts fail. The virtio device config space moves out from under us when MSI-X remains enabled, and/or INTx interrupts are masked if we don't ensure this. This un-breaks virtio devices that run out of MSI-X interrupts. Particularly a problem on uniproc x86, where there are only 8 or 9 vectors available, allowing for only about 4 virtio devices to use MSI-X.
