Intel IXP435 kernel issue

    Linux kernel:2.6.20.21 (timesys)

    I have Intel IXP435 demo board.I tested GbPCI to GbPCI throughput and
    GbPCI to IXP435 MII lan.but the kernel show up some error message.
    I try limit all network buffer 64MB, performance not bad.but, still
    show up error message.
    this message look like DMA and IRQ error.
    so, any comment?

    Thanks
