It's really getting better here. I really appreciate it and thank you
for your work.

But I still found a problem, sorry :(
Detaching and reattaching indeed works like a charm now. But when I
reattach the ethernet device I do not have internet connection
anymore. Of course I cannot have internet connection anmore, no
problem with this.

So I tried to bring it up again. Call me silly, but
I tried 'ifconfig pppoe0 up' first. And this dumps straight away.
I would not mind if this command yields an error or does not work. But
I think it should not kernel panik at all ;)

Here's the callstack of my fresh new coredump.
