    Well, the output below anwered my question about multiple MSI's from a
    single device :)

    So, over time at least, the interrupts have been spread over half the
    cores in the system. This is where the block diagram showing the socket
    and I/O slot connections would be useful.

    For the interrupts over a given interval, one can take snapshots at
    either end of the interval and then run them through beforeafter:

    I think that collectl might have something there too.

    I guess the addresses in use weren't sufficient to get interrupts spread
    across all 24 IRQ's.
