This is a symptom of a failure to insmntque a vnode after creating it, a new
requirement for vnodes in FreeBSD 7.x/8.x; previously, vnodes were
automatically inserted on the mount vnode queue and had their mount pointer
set up during getnewvnode(), but closing certain races motivated this change.
The reason I know this is that I remember adding two calls to insmntque to
nnpfs in my patches, so there are three possibilities: (1) I missed a call to
getnewvnode, (2) the patches I posted didn't include that change, or (3) the
patch didn't apply properly. I'll investigate this later today once I've
given my FOSDEM talk; chances are it's an issue with the patch.
