I have tried the "acpi=force" fix but it did not work for me.
I just built a new system with:
AMD Phenom X4
MSI mobo 880GM-E43
-ATI Radeon HD4250 GPU onboard (more on this below)
MSI nvidia GeForce 9400 GT
Ubuntu 10.04.2 kernel 2.6.32-30-generic-pae
I installed 10.04.2 and had the no shutdown problem. So I tried to load the ATI driver using System > Administration > Hardware Drivers to see if that would help.
Driver install failed the first time tried with a non-specific error. I tried again and the driver installed successfully. On re-boot the display was bad (see attached) so I went back to the stock Ubuntu driver. However, I did not get a boot splash screen. So I installed the MSI nvidia GeForce 9400 GT card I had and loaded he nvidia driver using System > Administration > Hardware Drivers. Splash screen now seen. Still had the no shutdown problem. So, doesn't seem to be video driver related as I had the problem with both stock and proprietary drivers.
Checked MSI for updated BIOS but I am very current with only 1 new rev available. It seems to be a very minor bug fix and would have nothing to do with my shutdown problem.
If I press Esc after selecting shutdown I see the text of what is happing during the shutdown process. The text seems normal and even gives a "shutdown" command at the end and then just hangs there. I must press the power button to shutdown the system.
Attached: uname -a, lspci and display screen shot with ATI driver.
