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.
