I have a 6715b that is experiencing the same exact problem. I made a
release from 8-CURRENT as of last night and I still see it. Just by
chance, I installed my normal kernel (for my other amd64 machine) onto
the ISO and re-burned and it worked (since I don't have if_bge on that
kernel). After selectively loading/unloading modules I tracked it down
to this.

Has any more traction been made on the BGE issue here?
