Hmm, perhaps (but then I'd like to try to keep the alarm timer
related changes in). In particular if your attempt to gate the
call to create_periodic_timer() on a flag was together with the
start time relative calculation that you had sent in patch form.
If it wasn't, it'd like to give that one a try first before going
the revert route.
