Kernel problem? ... Partition re-read send device delete events but miss
add new add events ... or possible sequence problem (re-add just before
old delete = to fast re-add) [remembering notes about hotpluging
anywhere in newer kernel change logs, but didn't look close to those]

... meanwhile do "sleep 2s; mdev -s" right after partition reread ...
shall do the job
