Hi,

kernel level irqbalance is not the right thing though (afaik it's in
feature-deprecation-schedule); please consider using the userland
irqbalancer instead (www.irqbalance.org). That also makes it entirely
easy to do what you want; since it's a daemon, starting and stopping it
follows standard Linux practice.
