Are these Rx FIFO or Rx Missed errors? These errors occur due to insufficient PCI bandwidth or lower size of the Rx descriptors. Note that in case of 82546, both the NICs shared the same PCI bus. Whats the PCI speed/width and how many devices are using the same bus? Did u try using a PCIX motherboard.
