I now test with test10pre4
Salut Henner,
I had a quick look into the source. As it always crashed in kfree_skb, 
I changed some lines in net/core/skbuff.c (see attached patch). But this
is not a cure - it only does not crash, at least not immediatly.
The section, I changed should report a bug - this reporting did crash the
machine. But it would be a cure, if we could fix this bug, that wants to
get reported
  Warning: kfree_skb passed an skb still on a list (from
<isdn_ppp_push_higher+0x298>).

Maybe, someone knows a bit more, what this message wants to tell us?

I tryed to connect with -lzs option, and a second time with noccp -lzs.
The second try did not report the warning, as expected. A ping to the peer
did bothtimes succeed.

Regards hartwig :-)
