ifconfig bge0 crashes kernel (on i386)

[Kurt Schreiner <ks%ub.uni-mainz.de@localhost>]

Hi,

after cvs update'ing -current half an hour or so ago, calling 
ifconfg bge0 during system startup crashes the kernel. Here's
the trace from the crash dump:

What's "interesting": after calling "reboot 0x104" from ddb the system
does _not_ reboot, but goes back to ddb...
