I recently had similar problems (specifically with the e1000 driver). When one hang goes down a send to the other interface will hang. This was when we were using the same socket to send on both interfaces, what resulted is that the socket buffer would fill up and cause the send to block. If you aren't using the same socket to send out on both interfaces you should be fine. the rather large hack that i used to get this to work on my system is below. basically it will not enqueue a packet when the interface is down. this may well do nasty things to tcp...

There's an old thread on netdev, occasionally resurrected, about this behaviour btw.
