Hi, I'm currently running 12.04 LTS.

I started with removing the following packages: liblzo2-2 uswsusp

I downloaded the mainline kernel packages from here: 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/
Installed the following three packages:
linux-headers-3.4.0-030400_3.4.0-030400.201205210521_all.deb
linux-headers-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb
linux-image-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb

Unfortunately this kernel is very unstable at the moment on my laptop. It is 
not even enable to shutdown properly.
When I click on hibernate in the Unity shutdown menu, it just locks the screen 
but does nothing else.

---

I also tried hibernation with the current kernel (linux-image-3.2.0-24-generic, 
x86_64) with uswsusp uninstalled.
Situation is the same. It sometimes resumes, but sometimes recovery hangs with 
a blinking underscore in the top left corner. 

Strange is that I can reproduce this om my wife's laptop which is a Dell 
Inspiron N5040:
http://www.ubuntu.com/certification/hardware/201104-7783/
I experience the same, recovery hangs with a blinking underscore in the top 
left corner. 

Based on that this may be a bug which is triggered by some component on
Dell laptops.
