[Tony Middleton <1500046@xxxxxxxxxxxxxxxxxx>]

I recently removed an LVM snapshot that had been in place for some time.
When I next rebooted the delay problem had gone away.

It seems this is a known problem.  There are a number of bugs where root
is on LVM and the delay causes boot to fail.  I don't have root on LVM
so boot did not fail but was unreasonably slow.
