This is likely the issue described in this message:

http://lists.freebsd.org/pipermail/freebsd-fs/2008-October/005217.html

The nfs fix has been committed to head and stable/7 (7.1-RELEASE has the
fix). The fix prevents system from panicing but you still can't access
the snapshot directory with readdirplus enabled nfs clients. As a
workaround you can disable readdirplus support if your nfs client allows
it.
