As it seemed quite strange that I had gone so backwards in the kernels and
suspension still did not work, I tried to change my PC's power supply, with
another power supply and with this other power supply my PC suspends correctly.
If I put back on the original power supply the problem comes back
I have tested various Precise kernels up to now but suspension fails on all
(3.1.0-1.0 3.1.0-2.3 3.2.0-1.1 3.2.0-1.3 3.2.0-2.4 3.2.0-3.9 3.2.10.18
3.2.0-16.25 3.2.0-17 3.2.0-20 3.2.0-23 3.2.0-24 3.2.0-25 3.2.0-32 3.5.0-17)
, it's quite weired as I am sure not long ago suspension used to
Sorry if it's taking long, but I am trying out some kernels to find out in
which kernel suspension used to work an in which it stopped working.
As soon as I find out, I will let you know.

@Christopher: ok give me some time to read all the stuff and I will provide the
information.
I used to be able to suspend my PC with Precise, after some updates it stopped
working, do not remember precisly at what after what update.
If it useful i can try to test various Precise old kernel
I tried out some kernels that were already on my PC to find out when suspend
worked, as I do not remember precisly when it stopped working.
Since kernel 3.2.0-17 suspend does not work.
As my PC has a linux kernel with the capability of /sys/power/pm_trace I tried
out this:
sudo sh -c sync; echo
Sorry in the dmesg file I have to hash matches entries:
[0.994801] bdi 1:14: hash matches
[0.994813] tty ttyS16: hash matches
but they are not in the same format as indicated in the DebuggingKernelSuspend
page.
So I'm not quite sure if the culprit of my problem is in these lines.

Carla Sella, thank you for providing the suspend information, and
further narrowing down which Precise kernel this regression began in.
Just to clarify, regarding your comments
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1059037/comments/8 :
Since kernel 3.2.0-17 suspend does not work.
Christopher, sorry I was not very clear.
On my PC I had kernels going back to 3.2.0-17, but with all of these kernels,
3.2.0-17 included, suspension does not work.
So I was not able to find a kernel with a working suspension.
If you think it's necessary I will install and test the older kernels
Just one question, I usually install kernels from here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/
Is this the right place or should I get them from somewhere else ?
Thanks.

Carla Sella, thank you for reporting this and helping make Ubuntu
better. Could you please provide the information following
https://wiki.ubuntu.com/DebuggingKernelSuspend ?
As well, regarding your Bug Description:
I used to suspend my PC without any problems...
Was this in Precise? If not, what
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.6 kernel[0] (Not a kernel in the daily directory) and install both
the linux-image and linux-image-extra .deb packages.
Once you've tested the
I installed kernel 3.6.0-030600 but it would not boot, the only thing I get is
a purple background that stays there forever.
I cannot do anything, CTRL+ALT+F1, CTRL+ALT+CANC do not work I have to switch
off the PC pressing the power button.

I installed kernel 3.5.0-16.25~precise1 for testing, so I also tried to
suspend my PC, It did not work.
Do not know if it matters, but I thought it would be a good idea to tell you.
Just for curiosity I also tried kernel 3.6.0-030600rc7, but suspention
did not work.
