Yes.
I see kernel panics when connection is terminated - but this happend

Sometimes to reproduce i need to connect->disconnect 50 - 60 times

OK. I CC Andrej and Eric, who diagnosed it in this thread:
http://lkml.org/lkml/2010/12/3/116
[unable to handle kernel NULL pointer dereference in skb_dequeue]
This should be also interesting:

Thanks for testing,
Jarek P.

I can't reproduce kernel panic now with houndreds of pppoe sessions that
connects-disconnects.
