Nicola, thank you for updating your BIOS. Could you please provide the results
of the following:
sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date
As well, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
the problem persists after the BIOS update.
I'll now try the fix suggested at

The problem persists after several months and ubuntu 12.04 updates.
I just updated to the latest BIOS (A17) following Christopher's suggestion.
Let's see if the problem persists.

Nicola, as per
http://www.dell.com/support/drivers/us/en/19/Product/latitude-e6320 an
update is available for your BIOS (A16). If you update to this, does it
change anything?

I installed linux-image-3.5.0-18-generic (version 3.5.0-18.19~precise-
proposed) from precise-backports, and after some hours of normal usage I
experienced the exact same freeze again. Now I am very puzzled... any
hint?

I stopped testing v3.7-rc2-quantal after a few hours as it was too
unstable (did not observe the bug, but I think that the observation time
was too short to reach any conclusion).
Then I installed http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/
I have been using it for about a week. I
The bug happened also in some cases where the computer was never
suspended after the last boot.
I now installed linux-image and linux-extra from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc2-quantal/
(BTW could not install linux-headers because of missing linux-headers*all.deb
package)
Nicola, thank you for attaching the kern.log, which contains a call
trace. Regarding the attachment, did you resume from suspend and then
this occurred? If so, is this problem reproducible if you restart the
computer and do not suspend?
As well, could you please test the latest upstream kernel
I confirm that the two bugs are separate issues. The symtoms of the
present bug occur also when firefox is not open, so it's not the same as
bug #1056337 which is reproduceable with firefox. Besides, clear
differences of the present bug are:
1) sysreq + REISUB never works (unlike bug #1060367)
2)
doing some search I've found that I need a kernel compiled with
CONFIG_PROC_DEBUG_INFO in order to see OOPs (right?), but then I tried
this:
grep CONFIG_PROC_DEBUG_INFO /boot/config-`uname -r`
and I get no results, so CONFIG_PROC_DEBUG_INFO is not set in the kernel
I am using (3.2.0-32-generic).
I've installed linux-crashdump and it seems to be running
$ cat /sys/kernel/kexec_crash_loaded
1
however I've tried the test crash with sysreq+c, the system crashes but
doesn't rebut (I waited a few minutes), and after finally power cycling
the machine I don't find anything in /var/crash/
By the way, I did an update between the original bug report and my last
comment, so the last kern.log that I posted was produced with linux
3.2.0-32-generic.

FYI, I actually managed to reproduce the symptoms described in my
comment #3 by visiting a certain page with firefox. I hence filed a
separate report as bug #1060367. The reason for opening a separate bug
is I am not sure that it's the same bug: in fact, with the firefox bug
#1060367 I manage to
Nicola, thank you for reporting this and helping make Ubuntu better.
Could you please capture the oops following
