I'd be assuming that you're not getting any interrupts through for those NICs. Could you please check /proc/interrupts, see if the interrupt counts related to the NICs can be made to increase? Also, the full `dmesg -s 1000000' output might help. We might also get some interesting info if you can compile your own kernel, build thsoe net drivers into vmlinux, capture the dmesg output. If it _is_ an IRQ problem then you might find that fiddling with ACPI helps: disable it in config or boot with `acpi=off', see if that helps. Also try booting with the `pci=routeirq' option. There are various options described under acpi= and pci= in Documentation/kernel-parameters.txt which it would be useful for you to experiment with. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
