The OP did state that the root filesystem is read-only.
It should be easy enough to mount root writable, populate /dev on this
filesystem then switch back to mounting it read-only.
There must be more than one way that a tmpfs can be active at the point
where it is forceably unmounted though. I don't have /dev on tmpfs and
get exactly the same error message at shutdown.
