[Bridge] Problem loading bridge.o

I encountered the same problem when trying to compile the kernel and 
modules with the bridge.o option. (I was using kernel 2.4.25.)

I could not get past the unresolved symbol errors even with "make clean; 
make dep; make bzImage", etc.

I found this post: 
http://lists.osdl.org/pipermail/bridge/2004-March/000200.html. The 
recommendation was to use "make mrproper" (BUT first save your .config 
file somewhere safe!!).  This approach worked for me and the bridge.o 
module loads without complaint.

Good luck,
Bob Dingman
