Hi Sephe,
Sorry for my later response...

Seems to be ukphy?

SMP problems do no longer occur. But when I do not assign a media (like
100baseTX) myself it crashes immediatly when running dhclient:

I uploaded crashdump here
http://leaf.dragonflybsd.org/~mneumann/bge_crash/
<http://leaf.dragonflybsd.org/%7Emneumann/bge_crash/>.
If I set media, it works well and only sometimes crashes, e.g. when I
reboot the computer.
