After upgrading to 15.04 , one computer is very, very slow to boot -several minutes, instead of ~20sec.

I do not know if this helps:

    No not beta, since 16th it was a release candidate, and now it's released.

I had the same error - it was related to the UUIDs in /etc/fstab. I had resized the disk partition, by deleting the swap partition, and then recreating swap. This caused the swap UUID to change.

List the UUIDs with:

 sudo blkid

And then check/fix any thatdo not match

 sudo vi /etc/fstab

On the released version 15.04. I resized the partition, and after that things really slowed down.

    @MichaelLindman I believe this is an attempt to answer the question. From what I gather it was a UUID mismatch and the list in /etc/fstab needed to be updated.

  • @java4africa you helped me a lot with your answer. How were you even able to relete the cgroup message with the solution. Jul 8, 2016 at 11:22

The problem was caused by bad swap partition reference in /etc/crypttab. It waited 90 seconds before giving up on that. For some reason swap was defined on an non-existing drive, once the line was deleted, everything works fine.
