You held down alt+SysRq and then typed REISUB one key at a time, and that didn't work? This: "Dec 5 09:31:21 deepblue systemd[1811]: shutdown.target: Fixing conflicting jobs shutdown.target/stop,shutdown.target/start by deleting job shutdown.target/stop" Looks like something is wrong but I am not expert - you might be onto something. I'm gonna do what you did and see what I get in Syslog. This still affects me in 15.04 and only when I run Chromium but every time I run Chromium SMH - I hate intermittent issues. Firefox does not cause this - go figure.
