Subject: cryptsetup + lvm on usb disk, unusable /dev/dm-* after
 suspend/resume cycle

  Greetings,

  Using an external usb 2 hdd with recent kernels with cryptsetup containers that
  contain lvm volumes. 

  After a suspend/resume cycle, with active lvm volumes, the mounted fs is "offline", 
  the dm-* devices don't respond to commands issued. No more access possible.

  Have to reboot to free the devices.

  Someone ever experienced that? Ideas to fix?

          Thanks,

                  Nils
