Because of wrong return value of .save_live_pending() in migration/block.c, migration finishes before the whole disk is transferred. Such situation occurs when the migration process is fast enough, for example when source and dest are on the same host. If in the bulk phase we return something < max_size, we will skip transferring the tail of the device. Currently we have "set pending to BLOCK_SIZE if it is zero" for bulk phase, but there no guarantee, that it will be < max_size. True approach is to return, for example, max_size+1 when we are in the bulk phase.
