The old interrupts shown with vmstat -i, on I386 on NetBSD 0.9 and 0.9A
show the device which is at the particular interrupt as well. This would
be a nice feature and would make the vmstat -i more useful, since I can't
always remember which device is at which interrupt.
Here is an example output.
%vmstat -i
interrupt count rate
clk irq0 76952025 99
fdc0 irq6 1 0
aha0 irq11 1050840 1
ed2 irq9 2933743 3
Total 80936609 105
