15.04 - very slow boot
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.

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.
