Regarding the second problem, I can confirm that I have the same messages in my log. It results from "formatting" the whole drive with BTRFS and not just a partition. So the drive has now no partition table which the kernel can identify. This does of course not change the fact that you can mount those drives without problems. You didn't see those messages before, so my guess is, that between Ubu 14.10 and 15.04 the kernel config was changed to make it more verbose. Do note, that those are not error or warning messages. The kernel is merely informing you about the fact, that it cannot identify the type of the partition table. Usually you can ignore those messages. Regards --Flo
