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? -- Regards, Lenky -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
