You are saying that something changes between each boot, but only giving one example so that we cannot see the change. That is not particularly helpful. The output above is a bit odd, but I think it is simply that the devices are all being examined in parallel so the per-device messages are being mingled together. Certainly 'sdd1' is on 'sdd', not no 'sde' as the message seems to show.
