I did not have exactly this problem but had some problems with ethernet.
I am using 2.2.16 and the system works fine.
But once I start using kdb the ethernet stops working.
The card does not pick up any packet from the network.
(I don;t even break into netif_rx). I am still looking into the problem.
I think the prolem might be with the card driver and somehow it gets triggered
by kdb. I am using rtl8139 module for my cards.
