Using the irqbalance service to dynamically change the IRQ-bound? It's
seems a software solution. In my old machine, there is no this
problem. I need some information to explain why. Maybe is the
apic_physflat mode only support distribute the interrupts to one
processor, but i am not exactly sure if this is right? Or my E5504
Machine's hardware issue?
