I guess it is not dm/block layer problem but USB related - can you check syslog if
the device is not attached after resume with another major:minor?
If this happens - you can free the mappings using dmsetup:
- try to force umount fs (if mounted), then run "dmsetup table" and manually remove
orphaned mappings using "dmsetup remove".
