Lee> There is no such thing as IRQ 177 and IRQ 185, correct?
With CONFIG_PCI_MSI (used to be CONFIG_PCI_USE_VECTOR) it's entirely possible to get interrupt numbers like that. On my dual Xeon system, I have /proc/interrupts that looks like:
CPU0 CPU1 CPU2 CPU3 0: 288964788 0 0 0 IO-APIC-edge timer 2: 0 0 0 0 XT-PIC cascade 4: 303 0 0 0 IO-APIC-edge serial 14: 67708 1 0 0 IO-APIC-edge ide0 15: 13 0 0 0 IO-APIC-edge ide1 153: 0 0 0 0 IO-APIC-level uhci_hcd 161: 1590294 0 0 0 IO-APIC-level eth0 169: 0 0 0 0 IO-APIC-level uhci_hcd 177: 0 0 0 0 IO-APIC-level uhci_hcd 201: 81 0 0 0 PCI-MSI-X ib_mthca (comp) 209: 2 0 0 0 PCI-MSI-X ib_mthca (async) 217: 2171 0 0 0 PCI-MSI-X ib_mthca (cmd) NMI: 57794488 57794274 57794272 57794270 LOC: 288981914 288981943 288981942 288981941 ERR: 0 MIS: 0
