Is that the fixed xen-hotplug-cleanup change?  The symptoms aren't quite 
the same; with the broken cleanup, there were lockfiles left lying 
about, so all the "block add" scripts were blocked waiting for the lock 
to be released.  In this case, everything is just sitting there; the 
hotplug never seems to get started.
