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. Greetings, Arjan van de Ven
