Looks like the kernel thinks there's an invalid label somewhere. Try
disklabel -Ii, that should write the label directly to the disk instead
of using ioctl()s. It may also help to zero the first couple sectors of
the disk before partitioning, in order to remove all traces of the old
apple partition table, which may confuse OF and others.
