I have a ruvo with a fresh installation of 12.04. When I try and shutdown the computer reboots. Until I upgraded (by doing a fresh install) I ran it with Ubuntu 10.04 and I didn't have this issue.

I have tried

sudo shutdown -h now 
sudo shutdown -P now
sudo init 0
sudo poweroff

All of these cause a reboot.

I have added acpi=norq to my grub file as suggested by someone in the first post below.

This is being used as a mythtv frontend and I would like the power button to shut it down. I have modified the button to perform a shutdown -h now, but this too causes a reboot.

I have studied the posts below and tried some of these ideas, but with no luck so far.

I built a system and it would always restart after shutdown. Around the same time I did 2 systems for others with the the same Ubuntu versions and they always shut down just fine. After trying some things in the O/S every now and then, nothing worked. I finally went into the BIOS under Power Management and shut off everything except leaving base ACPI enabled. Otherwise cool'n'quiet wouldn't work. I did change an S1 setting to S3, disabled everything else(except the base ACPI settting) and changed the control from BIOS to O/S(I figured this way after linux shuts down it won't have any ability to start the system but BIOS still may be able to). After I did these things it finally would shut off -after dealing with this for over 2 and a half years! It's really quite ridiculous but in my case, the blame seems to lie with an MSI motherboard. The two other systems that shut down like they're supposed to are 2 different models of Biostar motherboards.
