This bug affects a number of people. Based on having been able to get it working I have a guess as to what the problem is. First, here is what I did to get it working. Cron wasn't starting through upstart but it would start by hand. I went through this process to correct it: 1) Boot/login 2) sudo service cron stop This would result in th warning message, "unknown instance," since cron wasn't running. 3) Reboot At this point upstart seemed to start cron, however, if I rebooted again, it wouldn't be running. So, prior to rebooting I ... 4) sudo service cron stop Again. This (I'm guessing) gave it a clean shutdown because it's been working ever since. I'm guessing that, if state information about running services is kept somewhere by upstart, that data can be corrupted. I also think the way to corrupt it is to cut the power (or hard reboot) in the middle of the boot process - though now that it's working I can't seem to get it back into the failure mode - so this is a guess. I'm guessing this because I repeatedly hard reset the machine while I was getting it set up (it's a home theater PC running an unstable version of XBMC as the main session). Hope this helps.
