I have also found that sometimes "cupsysd" runs at 100% CPU too on bootup.

I observed this testing with virtualbox. Haven't tried bare metal. I will attach two screenshots, one showing the entry into single-user mode, the second showing the attempted exit. But the bits which seemed relevant are reproduced below; STEPS TO REPRODUCE: 1. Log in as root from a virtual console (in virtualbox: <host>-F1 and log in) 2. $ shutdown now # documented to enter single-user mode /lib/init/init-d-script: 2: /etc/default/whoopsie: [General]: not found ... ModemManager ... Caught signal, shutting down... ModemManager ... Could not acquire the 'org.freedesktop.Modemmanger1' service name 3. When prompted, enter root password ... 4. ^D (or type 'exit') ... /lib/init/init-d-script: 2: /etc/default/shoopsie: [General]: not found systemd-logind: Failed to start user service: Unknown unit: user@108.service systemd-logind: Failed to start user service: Unknown unit: user@0.service systemd-logind: Failed to start user service: Unknown unit: user@1000.service * Starting shoopsie shoopsie [fail] (HANGS) ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: upstart 1.13.2-0ubuntu7 ProcVersionSignature: Ubuntu 3.18.0-11.12-generic 3.18.3 Uname: Linux 3.18.0-11-generic x86_64 ApportVersion: 2.15.1-0ubuntu4 Architecture: amd64 CurrentDesktop: Unity Date: Tue Jan 27 15:46:46 2015 InstallationDate: Installed on 2015-01-02 (25 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Alpha amd64 (20150102) ProcKernelCmdline: BOOT_IMAGE=/boot/vmlinuz-3.18.0-11-generic root=UUID=96d674cd-12fb-4ad1-8d76-cffb545e6256 ro quiet splash vt.handoff=7 SourcePackage: upstart UpgradeStatus: No upgrade log present (probably fresh install) UpstartBugCategory: System UpstartRunningSessionVersion: upstart 1.13.2 UpstartRunningSystemVersion: init (upstart 1.13.2) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1415256/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
