[Bug 1052323] Re: [regression][lucid] system frequently reboots after update in august 2012, path via rtkit and AptDaemon

[Sebastian Heinlein]

I don't see why the reboot should be tiggered by aptdaemon.  You seem to
be confused by the aptdaemon log message which includes the words
"shutting down". But this only refers to aptdaemon itself and not the
system. That is why renamed the log messages.

** Changed in: aptdaemon (Ubuntu)

Bug description:
  My two lucid (LTS- long term support) systems now display recent reboots.
  I suspect the  kernel upgrade that was released end august 2012, but I an not sure.
  During the time of the reboot, the system was doing calculations in and atd/cron job.
  The signature of the reboots is as follows:
  1) rtkit-daemon starts logging that some processes become RT.
  2) after about 1 minute AptDaemon: INFO: Initializing daemon
  3) after about 5 minutes  AptDaemon: INFO: Quiting due to inactivity
  4) then, after about 30 - 60 minutes, I see the system reboot.

  This is a regression: I did not see this before.
  I have worked around by booting with acpi=off
