After 2/3 days of work on my laptop with suspend/resume next resume caused blank screen (network was ok, I will be able to login via ssh and try to something) and nothing helps only REISUB.
Resume was about 16:28 13/11/2012.
In kern.log I see PFIFO_CACHE_ERROR and anothers.

Please re-test with the latest kernel (e.g. 3.11-rc7). If problems persist, please include a log that includes the boot. If it hangs, grab dmesg via ssh, that will be most useful. (If it gets cut off, you can increase the log limit.)
How can I do it on UBUNTU 12.04?! Probably LTS does not support 3.11-rc7 kernel.
From my day work I switched from DELL LATITUDE E6510 to another laptop (because resume/suspend problems).
This laptop currently used by my 10 years old son to play Minecraft. So it's not easy to switch kernel... :-)

All of this brought to you with the power of the Google search engine. I highly recommend you check it out at http://www.google.com .
Thanks for suggestion about google.com. Unfortunately links your found are too general, first link even doesn't mention 12.04 LTS, 2nd says about new updates to kernel but also this is too general. I thought that you found for example distibution packages with 3.11-rc7, as I know 12.04 offers only 3.5.0-23.35. Do you know wheter 3.11-rc7 contains fixes for my bug?!

No clue. What I do know is that a whole bunch of stuff _has_ been fixed since 3.2, which came out nearly two years ago. The driver has undergone substantial changes since then. If you're stuck on whatever your distro provides, you should file the issue with your distribution, and we can close this one (although I suspect they'll just say "get the latest versions of everything and complain to upstream" or perhaps "nouveau doesn't work on new hardware on Ubuntu LTS"). At least one of the links I provided showed how to compile your own kernels on Ubuntu. I believe the other one provides packages that let you keep your LTS-based distro more up-to-date wrt hardware support.
No ability/willingness to test with new software after a month, marking this as invalid. Feel free to pursue this with your distro's bug tracker. If it does still happen with the latest software, feel free to reopen and add fresh logs.
