This is all a bit peculiar.  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.
