I also ran into this problem. In my case, I created the second encrypted partition after installing Ubuntu: (1) used fdisk to make partition, (2) run cryptsetup to create LUKS header, (3) edit crypttab to map the partition, (4) reboot.
In my particular case, I was able to work around the issue by specifying "initramfs" on all partitions as an option in crypttab. However this is an annoyance for partitions that are not critical for booting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1525724 Title: boot hangs with more than 1 luks device in crypttab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1525724/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
