I also have this problem and it's 100% reproduceable.

  As a quick and rough check, you can try to temporarily kill udev

  another instance of quite common error seen where lvm2's udev
  synchronization feature is not used (a device being opened and scanned
  from within udev rules while trying to deactivate it).

How should we go about determining _which_ udev rules are at fault and
what is the correct fix ?  My system is pretty vanilla so whatever it
is it is almost certainly part of the standard Debian install which
should be fixed, perhaps even by a stable update.
