This problem is reproduced on this external USB drive on my laptop using a quite light workload. It is not always reproducible and I had to change the way I work so I might not be able to reproduce this bug in the near time. There was another hang when shutdown tried to umount this drive: [374641.816086] INFO: task shutdown:20015 blocked for more than 120 seconds.
