Dual athlon MP 2000. I do not think that irqbalance is working correctly. Should most of the interrupts still be handled by cpu0? Is this a bug or am I misunderstanding how irqbalance works? Do other machines show about the same #'s with irqbalance enabled or do I have devices that can't be load balanced nicely?
