May I add a comment to this bug as this was marked on bug 1763611 to be a duplicate of this.
I can confirm comment #10 here. I got long boot time after upgrading from Ubuntu 16.04 LTS to 18.04 LTS but there was one release in between. I just followed the update announcements.
I use Mate.
I don't use LVM.1763611
I did solve my problem by editing /etc/initramfs-tools/conf.d/resume.
You can also read my comments #30 and #31 on bug 1763611. Maybe you find it helpful.
