Could you please give the patch at:
http://people.freebsd.org/~marius/dc_bitbang_delay.diff
a try? It's based on information gained from other drivers for
the same chips that there should be an delay after every write
when bit-banging the MII, which hopefully solves the bus wedging
you're seeing. So far I didn't manage to reproduce the problem
though, so I can't test whether the patch makes an actual
difference either.
