It was strange that it managed to even start booting the kernel at all; I can only guess that the hardware was not correctly initialized. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1609475 Title: recovery mode completely broken by systemd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1609475/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
