Dmesg after booting with kernel 3.7

Description of problem:

Hardware:
01:00.0 VGA compatible controller: nVidia Corporation G80 [GeForce 8800 GTX] (rev a2)

After upgrading to any 3.7 version of the kernel GNOME Shell becomes unusable with the nouveau graphics. Symptoms include very slow GNOME shell overview, screen corruption when hovering over icons, and lots and lots of dmesg output. Reverting the system to the last 3.6 kernel restores normal behaviour. My guess is there was some change introduced in 3.7 that is causing this bug.

Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-0.0.16-37.20120306gitf5d1cd2.fc17.x86_64

Works with kernels:
kernel-3.6.11-5.fc17.x86_64
kernel-3.6.11-1.fc17.x86_64

Fails with kernels:
kernel-3.7.6-102.fc17.x86_64
kernel-3.7.3-101.fc17.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Boot my hardware with nouveau driver and a 3.7 kernel
2. Enter GNOME Shell
3. Notice slow and corrupt graphics
  
Actual results:
Graphics are very slow and frequently corrupted; such as on hover over icons.

Expected results:
Fast correct graphics.

Additional info:
If any additional information is required I'd be happy to obtain it. I can run any tests required.

Dmesg after errors on kernel 3.8.3

Retested after latest update to kernel 3.8.3. Same problems, bug still exists.

Comment 3 Jon Dufresne 2013-05-29 22:35:49 UTC
This problem continues to exist with the F19 Beta live cd. The system is unusable with this bug.

Comment 4 Jon Dufresne 2013-07-12 16:51:07 UTC
This problem still exists with the released F19.

Comment 5 Fedora End Of Life 2015-01-09 17:41:45 UTC
This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 6 Fedora End Of Life 2015-02-17 14:46:58 UTC
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
