Hello,
tested with 12.04.4 stock image on 201109-9790 (BIOS A04)
I think we can narrow down this issue to nouveau itself, it works fine with the nvidia-331-update proprietary driver

This system can be suspended with nouveau, but X will crash on resume.
Many EE could be found in the attached log.

Steps for reproduce this bug:
1. Install 12.04.4, boot to desktop
2. Suspend it by using the "suspend" option in system menu
3. Press the power button to wake it up

Expected result:
* Suspend/resume works fine on this system

Actual result:
* System suspended
* On resume, you will see the desktop instead of the unlock dialog, and it freezes, the cursor is the only responding thing. A moment later, you will see the login screen, but it freezes again when you try to log in.

Since the proprietary driver works, blocker tags will be removed
