... and then you filed a bug ?
irqbalance might be seeing an MSI interrupt with a number greater than 255. I
encountered this several weeks ago while running an -mm kernel under rawhide.
irqbalance is hard-coded with an array indexed from 0-255 (corresponding to IRQ
numbers), and MSI numbers can exceed that value. irqbalance segfaults when it
sees an interrupt number larger than 255 because it attempts to poke an array
element that doesn't exist.
