Not good. Can you send me a copy of your tree or a patch, and a
complete boot log? I've seen the same issue, I just can't remember how
I fixed it at the moment. It's something to do with either the romcc
build parameters or failover code, I can't remember atm. Also, vt8601
is compatible with both c3 and p2/p3, right? Which are you using?

Check the datasheet, there's probably a bit somewhere in the LPC
controller that enables the smbus controller, you'll need to flip that
first, if you haven't already.
