I did some more investigations and came to the result that iwn crashes
in 'in6_ifattach_linklocal'.

When I disable ipv6, it all works fine. I did several reboots without a
problem.

To make this a bit more complicated, if I use only em0, the machine
starts normal. When I use iwn0 alone or together with lagg0 and em0,
the machine crashes during the boot process.  The crashes only happen
when IPV6 is enabled in rc.conf.
