Yes, correct, i am able to reproduce problem, i was scared i will be not able. Just when i am killing pppd on "server" side, flooding interface, it's happens.
I will try patch in next 30 minutes max. I have also bug, related to mirred to ifb0 and ethernet checksum offloading, but maybe it is fixed. I will try to remember, to tell about it. I dont have right now local computer with checksum offloading capable card, it also causing kernel panic, but i workaround it by ethtool, disabling feature.
