Ubuntu Precise 12.04 and 11.10 do not halt the computer completely, but 10.04 LTS does (Asus P5G41T-M)

I am using an Asus P5G41T-M motherboard with Core 2 Duo E5300.

I have tried Ubuntu 12.04 beta 2, the latest daily build of 12.04 and 11.10 (the latest official), both of which act in the following strange way:

When shutting down (using shutdown -h 0, halt) they get to a point where the splash screen dots are visible, but nothing more happens and the computer doesn't power off.

shutdown -P 0 works, halt and shutdown -h do not.

I've tried 10.04.4 LTS and it does behave correctly.

Using the newer releases, I've tried adding acpi=off and acpi=force to the kernel parameters followed by update-grub, but that didn't help.
Any suggestions?

I'm not sure this is a problem. shutdown -h means you want it to at least halt and the system decides whether to power off or not (see the man page for shutdown). -H means you want it to just halt, and -P means you want the system powered down.

If you don't want to, or can't, change the commands in your scripts or whatever, you might want to try this answer.
