Re: new if_bge/mii panic

Hi -
after I updated my kernel to today's sources (the last one was about 6
weeks old), I'm getting this panic:

 This problem might be caused by mii or bge, but I suspect that the problem
was caused by the following change:

At least MII related changes I committed change MII register,
sc->mii_media_active and sc->mii_media_status only.

#11 0xc0387122 in

There were significant changes in both if_bge and mii, so I'm refraining
from guesses for now.
