Shutdown does not work

[Craig]

ubunut 10.04lts
The shutdown does not work. Shutdown restarts the computer instead of shutting it off.
Can not shutdown through the terminal either, it just restarts instead. The only way to shutdown is by holding in the power button for a couple seconds.

Hi colleagues.

After upgrade to 10.04 from 9.10 my computer doesn't shut down. You can select and accept the option under GNOME but it doesn't shut down.

sudo update-grub

Hi Craig,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
