Greetings,
Apparently the first time mount_smbfs was executed, smbfs related modules
will be loaded by kldload(2); however, the result of the first kldload(2)
was always ENOENT even if smbfs.ko was successfully loaded. Only the later
run of mount_smbfs works.
It also interesting since manually "kldload smbfs" or even load smbfs
in /boot/loader.conf never run into ENOENT error. Furthermore, according
to various debugging printf() inserted in kldload() or linker_load_module(),
the return code is definitely zero. Any ideas about how this could happen?

mount_smbfs: kldload(smbfs): No such file or directory
