Hi, Not sure if this is a possible bug, but we are seeing the message "Dead loop on Virtual device BR0" a lot. We are using 2.6.10 and have now tried 2.6.11.5 with native ipsec, brouting, netfilter and HTB queuing enabled. If I shut down the ipsec tunnel, this message goes away. Can someone please explain what it means and whether it's a bug? Please let me know if there is any more information you need. thanks, Andrew.
