Description of problem:
On all of the 3.5.x kernels that have reached Fedora 17 stable, I've been encountering this problem that I never had with any kernel previous to it. I resume my laptop from suspend, and in less than 5 minutes, the screen goes black, and some dmesg-style messages related to nouveau appear. Then it seems to try to recover, but alternates between the black screen with the nouveau messages, and a messed up unusable screen with my work/applications. Since I was unable to do anything else, I've attached a photo and a video of what I mean. In the photo, you can see the messages related to nouveau failing. In the video, the alternating between to and from the kernel messages can be seen.

Version-Release number of selected component (if applicable):

How reproducible:
100% on my hardware.

Steps to Reproduce:
1. Boot with a kernel from the 3.5.x branch from Fedora stable repositories
2. Suspend
3. Resume from suspend, and do something for a brief period (if I do nothing, nothing happens: it seems to be only when I'm doing stuff).
Actual results:
Computer becomes unusable and alternates to a black screen with dmesg-style output.

Expected results: This is not expected to happen.

Additional info:
Since the output indicates that this has something to do with nouveau, here's the relevant line from `lspci -nnvv` for my graphics card:

FYI: This bug still happens with kernel-3.5.3-1.fc17 from updates-testing
Comment 5 Gerard Ryan 2012-10-08 08:08:10 EDT
This no longer happens from kernel-3.5.5-2.fc17. Closing issue! :)
