Hrm, the problem apparently is that while when probing, the PHY
still knows about the media it supports, it just has forgotten
about it after the reset during attach. There was a change prior
to 8.2 which would turn this from silently being ignored (which
generally might or might not work) into resulting what you see
now (the upper layers arguably shouldn't trigger a panic in this
case though). I can't remember a change to either bge(4) or
brgphy(4) between 8.2 and now which could trigger this though.
Have you tried to set the loader-tunable hw.bge.allow_asf to 0?
The default for that option still is different between 8 and 9+.
