OK, the last comment was a bit premature. After rebooting another time or two, it seems that disable_dad did NOT help for me.

I can confirm that IPv6 on Ubuntu 15.10 is basically broken out of the box... at least, the DHCPv6 is broken out of the box due to this issue.

[Touch-packages] [Bug 1453912] Re: systemd does not unlock dm-crypt password
*** This bug is a duplicate of bug 1432265 *** https://bugs.launchpad.net/bugs/1432265 Unfortunately this is pretty easy to reproduce. I installed Ubuntu Server 15.10, set up an additional partition and formatted it with LUKS, and added to crypttab. That is all it takes to make the boot process hang while it asks for a password. It appears that if the partition is unlocked in the initramfs, then it works. The initramfs cryptsetup is ok. But if initramfs doesn't unlock it - i.e. it's not the boot drive - then it's up to systemd to do so, which doesn't work. Oddly enough, if I reboot then I can momentarily see the password prompt just before the system reboots. Of course by then it's too late. :( -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1453912 Title: systemd does not unlock dm-crypt password Status in systemd package in Ubuntu: Confirmed Bug description: Since upgrading from version 14.10 to Kubuntu 15.04, my system does not boot normally any more. Maybe it's only a stupid oversight on my part, but not being a systemd pro, I'm currently at a loss of how to debug this any further. Hints and pointers to appropriate documentation are welcome! Kubuntu 15.04 quickly boots to a specific point where it seems to try to enable a dm-crypt partition which also carries /home, beside other data, and simply stalls. I'm not asked to enter my crytpdisk password and I also cannot enter it blindly without being asked. You can see the point where it stalls in the attached "screenshot" (photo of my screen). I can then press Ctrl+Alt+Del to cleanly restart the system but I could not find a way to get beyond this point with systemd. Using the alternative boot option with upstart works flawlessly. (Although booting with this boot option is really slow and it takes a while to reach the graphical login screen - it basically looks as if the system is waiting for some name resolving timeouts during boot, but that's a different issue, if've not debugged it further and maybe it's just gone once systemd works to boot my machine.)
