I've posted this bug over on Launchpad for Ubuntu, but this issue is happening in both Ubuntu 12.04 and 12.10. I upgraded to 12.10 hoping to fix the issue. Additionally, I used to use Arch Linux (kernel 3.6) and I was having the same issue. My laptop, Dell Studio 1569 will not shutdown in Linux. I can shutdown from either a graphical user interface or a terminal but the outcome is the same when I shutdown or restart. The kernel complains about a CPU Soft Lockup. The kernel says either Will Now Halt or Will Now Restart but never does. It simply says that it has some sort of CPU stall. See here as well: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1072350

Do you also get a traceback with the soft lockup message ?
No.
Ok first thing then is to work out if its a platform problem or a driver thing and if so which drivers. You should be able to boot the machine with the boot option init=/bin/sh and get nothing running but an initial shell, then type poweroff -f at the command line to power the machine back off. (you may need to ask the Ubuntu forums how to do this as I'm not that familiar with Ubuntu specific bits) If that fails then it may be tricky, if that works then it implies one of the other drivers is getting stuck - and that is something that can be hunted down methodically.
Okay, so that method allows my laptop to shutdown completely. I had to remove "quiet splash" to replace with init=/bin/sh but it does shutdown using that method. Another point of information I just noticed. If I shutdown my laptop within a few minutes of turning it on (lets say less than 5) the computer powers off no problem. Otherwise, if I leave it running for an extended period (or normal period of time) it gets stuck during shutdown.
UPDATE: I am now also getting a hard cpu lockup at shutdown. The problem is random. I was able to get a picture of my screen but the output wasn't displayed in any log that I could find. http://imageshack.us/photo/my-images/203/imagekyr.jpg/
Okay additionally, standby does not work.
Did this machine come with Windows, and did that shutdown properly? If you saved your windows partition, that would be useful for comparison...
Yes, but I've since reinstalled windows and different distros of Linux. I do have a Windows partition.
Update: no ACPI functions seem to work with the exception of the backlight. Suspend fails, shutdown and restart still fail. Any help is appreciated.
Additionally: all ACPI functions seem to work okay within the first few minutes of the machine running. However, if I shutdown say 5 minutes after using the computer, the ACPI functions fail. Confirmed that this bug happens using Slackware 14, it's got to be in the kernel.
Hi Nathan, Thanks for the report. Can you please try to identify which kernels work and which don't(e.g. 3.0, 3.1, etc.)?
Hi Nathan, Is there any update about this bug?
