Result with both patches: there is no immediate crash when setting all
sky2 interfaces down, but I get the following messages repeated roughly
every second:

and the network interface fails to work (no ping, nothing with tcpdump,
etc.).

Does anybody have an idea on what might be wrong in sky2_down?

best regards,
