Description Alex G. 2011-02-02 18:50:40 UTC 
Description of problem:
The display freezes, with only the mouse pointer responding.

Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-0.0.16-11.20100826git065576d.fc14.x86_64


How reproducible:
Always; random freeze time between 5 min and 24 hrs, only when the display is active.


Steps to Reproduce:
1. Use computer as usual.
  
Actual results:
Display freezes.
The last lines of dmesg show:

Expected results:
Computer prints money.

Additional info:
Keyboard does not respond, pressing CapsLock does not toggle the keyboard LED.

Remote login via ssh still works, however, unloading nouveau as described here:
http://nouveau.freedesktop.org/wiki/KernelModeSetting
does not work:
#echo 0 > /sys/class/vtconsole/vtcon1/bind
#cat /sys/class/vtconsole/vtcon1/bind
1

X process stuck at 100% core usage.
Killing X or kdm does not restore the display.
The only way to recover from this error is to reboot the system.
Comment 1 Matěj Cepl 2011-02-04 08:29:51 UTC 
Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command after the crash but before reboot, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

AAAAAAAAAAAAAAARGH!
Comment 11 Alex G. 2011-02-28 21:14:18 UTC 
Booting with nouveau.noaccel=1 seems to fix the problem. I'm not seeing any performance hit on regular desktop usage.
Comment 12 Brad Hubbard 2011-04-06 05:12:09 UTC 
I will try nouveau.noaccel=1, I just got hit with this again xorg-x11-drv-nouveau-0.0.16-11.20100826git065576d.fc14.x86_64 Seems to usually get me during a transition between desktop, screen locks "mid-slide".

Comment 13 Alex G. 2012-07-11 07:36:38 UTC 
I haven't seen this problem since F16, and F17.
Comment 14 Fedora End Of Life 2012-08-16 12:44:51 UTC 
This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

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

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached 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 to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

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.

The process we are following is described here:
