Comment 18 for bug 1339249

Thanks Guys!!! Exactly the same issue - hangs forever with "starting enable remaining boot-time encrypted block devices".

As it was mentioned here - I also was running my Kubuntu 14.4 for a long time with sleeps, but without reboots on Thinkpad T440p. Then I've restarted it with connected by USB phone (as a storage, not as MTP device). I don't fully remember, but most probably I've disconnected the phone during the reboot.

Ctrl+Alt+Del helped.
