I can fix irqbalance no problem, however I like the kernel approach as
well, since it's not just irqbalance that moves irqs, sysadmins tend to
do it as well.... so how about both?
One thing we probably should do, and that would help irqbalance
immensely, is to export a bitmask for which cpus an interrupt CAN go to,
next to where the current binding interface is. I'll check into that
Hidetoshi: would it be possible to send me a /proc/interrupts file of
that machine?
