With iwlagn and r8169 blacklisted see what interrupt number the et131x gets (cat /proc/interrupts) and see if it goes up whenever you send/receive stuff. If not then I don't think its an et131x problem but an IRQ routing problem (eg a bad BIOS table, or a kernel bug elsewhere) > I do not think i am yet at a point where git bisect would be useful. Agreed.
