I have a machine running Ubuntu that reboots itself every 20 minutes or so. I watched the output of the sensors command and none of the thermal sensors or high (about 38.0C). What else could cause this issue? Which logs would help me?

Run ls -ltr /var/log to see which log files were modified around the time of the reboot. /var/log/messages may contain a clue just before the reboot, as could other log files such as cron.
