I'm not sure I saw it pass yet. But I wanted to note that removing the network-manager and network-manager-gnome all together and switching back to good old config files "/etc/network/interfaces" is a workaround for this problem as well.

I am facing (faced) the same problem and solved it this way.

My case:
Asus P5K Pro (Marvell88E8056® PCIe Gigabit LAN controller featuring AI NET2)
Ubuntu 10.4.1 amd64

I think I had the problem before without it leading to trouble, probably due to the fact in before cases that part of the network wasn't used if the perpetrator was powered down.
When changing that context the network appeared unusable when this computer was powered down, apparently caused by the traffic flood of the "zombie" NIC.
