(I would load the kld into gdb to get a better trace but I forget how) Hmm.. Interestingly I waited 5 minutes or so and tried umounting again, the first attempt failed, but the second worked. Mucho weirdness. Also, mount_smbfs doesn't seem to properly detect if libiconv is in the kernel. I have it as a kernel option, but it tries to load the kld. This fails, so mount_smbfs fails first time around, but second time I attempt the mount it doesn't bother trying to load the module and it works.
