What do you see in /proc/interrupts on the host (before you unbind and after you bind to pci stub)? The host dmesg shows other possible devices sharing that interrupt: $ grep "IRQ 19" jZu3WKZW 482. ahci 0000:00:1f.2: PCI INT B -> GSI 19 (level, low) -> IRQ 19 578. ehci_hcd 0000:02:01.3: PCI INT A -> GSI 19 (level, low) -> IRQ 19 623. uhci_hcd 0000:00:1d.1: PCI INT B -> GSI 19 (level, low) -> IRQ 19 795. ivtv 0000:03:09.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 814. IRQ 19/ivtv1: IRQF_DISABLED is not guaranteed on shared IRQs 955. pci-stub 0000:02:01.3: PCI INT A -> GSI 19 (level, low) -> IRQ 19 thanks, -chris -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
