A little question. Why do we want to bind irq of eth0 to a single CPU ? imho it will casue slowdown of some situation. Why don't we leave scheduler to select CPU for processing IRQ ? - Gabor - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
