I haven't really followed the whole thread but AFAIR, irqbalancing is done by the scheduler on kernel>2.6 where the kernel dispatches interrupts on one processor for a while and then randomly switches to another processor. You don't need to run irqbalance specifically to make the kernel do this. ./h -- Kernelnewbies: Help each other learn about the Linux kernel.
