Bug Description

== Precise SRU Justification ==

This bug prevents desktops and servers from shutting down properly. This bug affects many different systems and a number of users. This bug is a high priory for servers, since physical access would be needed to shut the server down.

== Fix ==

Commit a3dd3323058d281abd584b15ad4c5b65064d7a61
Author: WANG Cong <email address hidden>

    kexec: remove KMSG_DUMP_KEXEC

commit c22ab332902333f83766017478c1ef6607ace681
Author: Matthew Garrett <email address hidden>
Date: Mon Mar 5 14:59:10 2012 -0800

    kmsg_dump: don't run on non-error paths by default

comit a3dd3323 allows us to cleanly cherry-pick the actual fix, commit

== Impact ==

A high number of desktop and server systems are affected as well as many users.

== Test Case ==

A test kernel was built with these two patches and tested by original bug reporter as well as other bug commenter's, which were also affected by this bug. These patches now allow the system to shutdown properly.

== Original Bug Description ==

I'am testing 12.04 (3.2.0-17-generic) and shutdown does not work. If i tray to shutdown or restart ther is the logo with the wording and the whites and the Orange points but it freezes. If it is frozen ctrl+alt+del show no effect. The hard drive turns off but the CPU and the display will continue. I have tried the following terminal commands, but the result is always the same.

sudo shutdown -h now
sudo shutdown -P now
sudo halt
sudo poweroff
sudo reboot

The problem occurs on a Acer TravelMate 8473T
Sorry that I can give no further information. This system forgets that there was a problem, because the hard drive turns off. This problem does not occur under 11.10

Would it be possible for you to test the latest upstream kernel? Refer to . 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.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

Shutdown does work with Mainlinekernel 3.3.0 on my Acer TravelMate 8473T with an UEFI Mainboard.

The kernel freeze is in a week. Will Linux 3.3.0 still be included in Ubuntu 12.04? I ask because my proprietary driver for Broadcom wlan does not work with this Mainlinekernel. Or may be backported bugfix in linux 3.2.0-20?

As I experienced the same issue (hangs on reboot, while shutdown is fine) with the latest official kernel, I just tested this patched kernel. Now uname -a reports:
Linux ubuntu-Latitude-E5520 3.2.0-22-generic #35~lp944772 SMP Fri Apr 6 16:15:09 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Unfortunately this patch did not fix my SandyBridge Dell Latitude E5520 behaviour: shutdown is still fine, reboot hangs exactly the same way as before.

As I still have all beta 1 and 2 kernels installed, I can re-test some previous versions if it makes sense, as I'm pretty sure there was at least one working fine.

The patched kernel, linux-image-3.2.0-22-generic_3.2.0-22.35~lp944772, solved the issues with freezing from resume from suspend!

I confirm what Alexander experienced: with linux-image-3.2.0-22-generic_3.2.0-22.35~lp944772 even my system does not freeze anymore when resuming from suspend.

But I'm not lucky as Rikard, as I have a freeze during shutdown, if I choose for a system reboot.

I hate to add another comment, but the issues I mentioned in #97 and #96. The kernel panic/oops is related to the NVIDIA proprietary drivers (I did install x-edgers ppa, that did not help), not the kernel (both 3.3.1 and 3.4.0 RC2 boot without the drivers).

Hi, in the mean time I performed a full reinstallation, and eventually I just got the latest updates, including the following:
Linux Max-Latitude-E5520 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Sadly, even kernel 3.2.0-23.36 didn't fix my issue: shutdown is fine, rebooting hangs on shutting down process.

I think I should open a new bug now, as suggested by Joseph.

Just the update to Linux 3.2.0-23-generic was recorded. Power off and reboot fine!

I thank you all for everything! 12.04 will be a great release.

I have all updates till 2012.Apr.12 (including), but i still cant shut down (and restart) my laptop normally. It always hangs.
I tried Ctrl+Alt+T and sometimes it shows last entry something like "deconfiguring network interfaces ....OK"
once i got another line something like "detaching swap", but cursor was blinking in place where OK should have been. I waited few minutes but nothing.

Can you open a new bug for your issue? That way we can gather specific details on your hardware.

For those who are having reboot hangs like me, I opened a new bug and also posted a workaround there.
Please check if this workaround works for you as well, to identify if it's the same issue.
Note that on my machine only 64bit version hangs on reboot, precise 32bit works fine.

Same problem with 3.2.0-24-generic-pae (Lenovo T61).
Shut down does not completly power off the pc, it just turns off the monitor.
Suspend works fine.

Solved on my system with the following workaround. Run:
sudo xdiagnose
and disable VESA framebuffer driver and disable PAT memory.

Shutdown does not work for me on 32bit 'precise'.

For me issue was resolved via switching from proprietary nvidia drivers ver.295.40 to nouveau driver.

When using nvidia drivers shutdown issue occured when I run some video in VLC. I was unable to switch to tty1 (just blank screen) -- in this case system hang at shutdown. If I was still able to go to tty1 then pc shuts down perfectly (for example immediately after logging in).

I tried to switch to older nvidia drivers like 275.x: seems to work but I decided to reinstall ubuntu from scratch. Now shutdown works for me ok.
