Are you certain that bge is a kernel module, and not statically built into your kernel ? Are you using /boot/loader.conf to load the module ? What does kldstat show ? I ran through all of the case scenarios I can find, and the rc.d scripts would not call ifconfig on an interface that did not already have a kernel module loaded. If you know something here that I do not, please share. :) --Thanks! --Dave H > > Best regards > =A0 Oliver > > -- > Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b.
