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)
