Well, for my dualCore notebook, dualCore MythTV box, and QuadCore
desktop, the behaviour of the existing, working, 32-bit kernel
IRQBALANCE code outperforms the userspace utility.
Mostly, I suspect, due to it's much faster response to changing
conditions. That's something the external one could try to match, but
at present it seems tuned specifically for high-traffic network
servers, not for the average notebook or desktop.
I'd really like to see what it's doing before commenting on this;
at minimum can you give me the /proc/interrupts of the system?
It might a simple bug or simple missing item, not a total "scratch the
full system".

Next time I'm doing something significant there,
I'll collect some data for you. Got other work now.
But it does make sense that this mechanism cannot be longterm for
a desktop. Intensive loads come and go quickly there, and the
interrupt handling has to respond in a timely fashion.
It's not like a server where loads generally increase/decrease gradually.
