If you still experience this on recent kernels, please try
ethtool -A ethblack autoneg off; ethtool -A ethblue autoneg off
The hypothesis is that the gnubee sends ethernet "Pause" frames to the switch, and that causes the switch to zone-out.

For the record, as I don't expect it to be fixed, here is the message I get when the GnuBee starts messing with the ethernet switch, which brings down all communications on that switch until I unplug the GnuBee.
