Bug Description

On xubuntu 12.04.3 64 bits, with Dell computer (7010 and some other optiplex), reboot hangs and display terminal :

acpid exiting
running unnatend : ...

I had same problem on 32 bits 12.04, but solved by adding "acpi=force reboot=pci" in /etc/default/grub
Here, on 64 bits, tried that and didn't work.

I also tried every other reboot parameter, without success.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

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.

Also, the 3.15-rc1 kernel is now out as well. Can you give that a test:

Didn't try these kernels yet but, for posterity :

All reboot tests are made with console mode (CTRL + ALT + F1) and CTRL + ALT + SUPPR

Sometimes, reboot hungs on apache.
I had a problem with apache2, which doesn't want to pass because of there wasn't "ServerName localhost" options in /etc/apache2/apache2.conf.

Still not clean reboot :

Before, every computer, at every time hangs.
I added "reboot=pci" kernel option in /etc/default/grub, and now, if a computer was rebooted few minutes before a new reboot try, the problem comes 1 times on 10.

It hangs after all K** in rc6.d.
I noticed that, the difference between computers that reboot properly and those which do not is a log line :

"Rpcbind terminated on signal" : when this line apear, one second later, the computer reboots properly.
I googled it and saw that RPCbind has a report with NFS and that, that is "S20sendsigs" which send this signal.

Here my rc6.d dir :

I don't know where autofs is shutting down. So i thank that umountnfs.sh was executed before autofs closed.

So, I created a script sifrebootdefrozen which contains :

#!/bin/bash
service autofs stop
sleep 2

And place it in K02. When it is executed, i saw on screen "autofs already closed" or something like that. So that's not the problem.

If I wait for 30 minutes or more, a new problem appears, reboot hangs on black screen, only "acpid exiting" diplayed.

Hi
I have serious reboot problem since a long time.
I discovered that if i "service autofs stop" before reboot, there's no problem with reboot.

Here my autofs confs :

# dpkg --get-selections | grep autofs
autofs install
autofs-ldap install
autofs5-ldap install

# apt-cache policy autofs

When i desactive one of these inputs (or /net or /auto_home), reboot works fine.

Here's my logs since the last reboot ::
