Thanks for looking carefully at this!
It looks like the problem is that we had /tmp mounted as tmpfs, then
mounted as tmpfs again on top. We've had this for a long time
(unintentionally), but it hadn't surfaced as an issue until now - we
didn't even realise.
After removing the duplicate mount setup so that /tmp is only mounted
once, the system shuts down.
