problem with shutdown ubuntu 11.10 x64

[Aaron Sun]

After upgrade 11.10 x64, I have problem with shutdown, it just hanging there with a ubuntu logo, then I have to press the power botton to shut it down.

I tried 3 ways to shutdown, they are all the same.
1. From menu "shut down ..."
2. shutdown -h now
3. shutdown -P now.

Please help!!!!

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). 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.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.3-rc6 fixed the issue, the tag would be: 'kernel-fixed-upstream-v3.3-rc6'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I installed v3.3-rc6-precise, but ubuntu can't boot any more, I'm now trying to restore to the previous kernel.

This problem still exist after upgrade to 12.04, really annoying that ubuntu can't power off, every time I have to press the power button! I have tried so many different "fix" according google search, none of them work, even don't know where to start trace this problem.

Could you help to give me some hint at least? I seems lots of people has the same problem.

Ubuntu 11.10 on Dell XPS 15z. Dual Boot with Windows 7 Home, bumblebee stable installed.
I have the same problem as Aaron, when i try to shutdown the computer (either from the main menu or from a terminal) i have to force it by pressing the power button. This problem started after the latest update about 4 days ago. Now i'm using the 3.0.0.19 kernel from the official packages. After this update i'm experiencing also other strange problems, and i'm not sure about their relationship with the one here discussed. For example i cannot run succesfully the update-grub command: it does not terminate (it starts but does not terminate, and it is blocked on "Found memtest86+ image: /boot/memtest86+.bin"). Another problem is that sometimes i cannot kill a command (via CTRL+C keyboard combination), it seems that the OS does not catch the input. I experience this problem when i try to kill update-grub command too. Final I'm not able to succesfully uninstall virtualbox package, it blocks on "Stopping virtualbox kernel modules".
As i said i really don't know if all these problems are related each other, but i hope there will be a solution soon.

I'm having this problem with 12.04 too and I'm also using bumblebee, but it doesn't always happen, but it happens often. Could bumblebee have something to do with it?

[Aaron Sun (hisycg)]

I found a temporary solution:

sudo cat /etc/default/grub

#GRUB_CMDLINE_LINUX_DEFAULT="acpi=off splash"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

sudo update-grub
