I experience the same issue as OP after a clean install of Ubuntu 16.04 4.4.0-72.
Nothing can be done in recovery mode that takes longer than one minute, otherwise some timeout fires, console spews several screens of messages indicating processes being stopped, and it loops back into the recovery mode menu; however now there is no keyboard or at least no keys respond other than ESC, thus no way to navigate the menu even if were now operable. Hitting the ESC key at this point causes the following text to overwrite the first menu option: "sulogin: input overrun at /dev/tty1t" But perhaps that is just an artifact of the unwanted and unrequested shutdown of system daemons. Nothing more can be done at this point, a hard reboot is necessary. This is repeatable, i.e. the same symptoms occur at each entry to recovery mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1636503 Title: recovery mode gets borked after some time out To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1636503/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
