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 :

lrwxrwxrwx 1 root root  16 oct.  16  2013 S90reboot -> ../init.d/reboot

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.
I tried every "acpi=" kernel options in /etc/default/grub. Still same problem, so i removed acpid (with its dependence acpi-support)

apt-get remove acpid (key words for googling)

I don't have acpid log line diplayed. Acpi is clearly not the problem too.
So i excluded every others parameters, i can now test kernels in a cleaner way.

Best regards.

Title:
  Reboot hangs with Dell computers on 64 bits

Status in “linux” package in Ubuntu:
  Confirmed

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.
