You don't have irqbalance running by chance do you? Because this sounds exactly what it's designed to do.
https://github.com/Irqbalance/irqbalance
"Irqbalance is a daemon to help balance the cpu load generated by interrupts
across all of a systems cpus. Irqbalance identifies the highest volume
interrupt sources, and isolates them to a single unique cpu, so that load is
spread as much as possible over an entire processor set, while minimizing cache
hit rates for irq handlers."
