Probably it isn't LVM or some modern version, which isn't supported by
module. With enable kern.geom.linux_lvm.debug=1 module will complain
only if it will find magic string "LABELONE" in the metadata.
You can check what is stored in the metadata with the following command:
# dd if=/dev/ada1s1 count=1 | hexdump -vC
