As mentioned in previous postings, this happens when the driver checks
the interrupt status of the NIC and when this status was not network
related (it's not exactly like this but it serves the purpose). People
wrote to check your system for strange PCI interrupt problems. You should
check following settings to narrow down the problem:

ip -s -s link show dev eth0 [and check for the RX and TX errors]
cat /proc/interrupts [and check for abnormal high raise of interrupts
                      during network load on any of the devices]

If you get pissed off by the warnings, just adjust the debug in the
source code or insmod with debug=0 because most drivers set debug=1
when insmod'ing if you don't explicitly specify it.

Cheers,
Roberto Nibali, ratz
