Public bug reported:
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
