Description Chad Feller 2011-10-01 00:01:37 UTC 
Description of problem:
Upon composing an email in Fedora, typing got slower and slower (meaning what I was typing in was lagging in showing up on the screen), until the entire screen finally froze.  After waiting for a minute, the screen didn't unfreeze.  I SSH'd into the workstation from another machine and saw this in 

dmesg:

[23912.004365] [drm] nouveau 0000:07:00.0: fail post-validate sync

[23912.004405] [drm] nouveau 0000:07:00.0: validate: -16

and this in my Xorg.0.log:

xorg-x11-server-Xorg-1.10.4-1.fc15.x86_64

How reproducible:
Only happened once so far, but this is a relatively fresh less than 48 hours Fedora 15 installation.
Scratch the above, it just happened a second time w/in an hour.

Additional info:

It just happened again while typing in this bug - thankfully Firefox saves form data.  =)

Here is the info from the second crash (I SSH'd in from another machine while the screen was locked up):

Comment 2 Chad Feller 2011-10-01 00:11:24 UTC 
Also, it should be noted that the lockup is so bad, that I can't just kill the X server, but I actually have to reboot.

Apologies if the output above is a little long, perhaps I should have created an attachment.  (I had increased the size of the text input box, so it didn't seem as long to me as the lines weren't wrapping.)

Comment 11 Chad Feller 2011-10-05 21:09:36 UTC 
Happened again (3rd time now).

Attached the logs (as I should have done the first time), Xorg.0.log (comment #10) and dmesg (comment #9).  

A few notes:

I saw the ttm_validate failures _yesterday_.  

Yesterday, the rate at which my text was showing up on the screen started to slow way down, at which point I typed dmesg and saw the ttm_validate failures, but my workstation didn't lock yesterday.  It recovered and everything went back to normal.

Today, my workstation slowed way down and spit out this:

[420215.011820] [drm] nouveau 0000:07:00.0: fail pre-validate sync
[420215.011833] [drm] nouveau 0000:07:00.0: validate vram_list
[420215.011910] [drm] nouveau 0000:07:00.0: validate: -16

after locking up.

Comment 18 Chad Feller 2011-10-27 22:16:15 UTC 
Wanted to add a few notes to this:

I disabled "desktop effects" in KDE after the last lockup, and the problem has not happened since.

Although desktop effects were enabled, each time the lockup occurred, I wasn't doing anything fancy, but in fact just typing text.  Three of the lockups I was filling in a form box in Firefox, once typing into pidgin.


Not sure if this is related: on my home workstation w/:

01:00.0 VGA compatible controller: nVidia Corporation G96 [GeForce 9500 GT] (rev a1)

I was also running desktop effects.  Didn't see any lockups there, but noticed that dmesg was littered with numerous lines like this:

[356514.599405] [drm] nouveau 0000:01:00.0: multiple instances of buffer 127 on validation list
[356514.599427] [drm] nouveau 0000:01:00.0: validate_init
[356514.599429] [drm] nouveau 0000:01:00.0: validate: -22

I turned off desktop effects and the problem went away.  Not sure if that is related here or not.

I have this too. Looks like random freezes, not very often. Usually it is possible (and needed) to reboot using sysrq keys.

drm.debug = 0x04, xorg logverbose = 7.
xorg.conf is absent, however some keyboard and mouse configuration files are present.

I'll try to reproduce this with debug kernel.

Xorg.0.log from nouveau crash

I am having this same issue on my Asus laptop. This is my Xorg.0.log from one such crash.
Comment 23 Jaroslav Franek 2012-03-01 20:30:16 UTC 
Having the same issue in F16 and probably in F17, but F15 works fine.

F16 experience (pretty bad):
can install in graphic mode (anaconda), used network install to pull newest version, but then after reboot firstboot froze after few seconds, so I can only use runlevel 3.

F17 experience (even worse):
cannot even install in graphic mode (anaconda).
used F17-Alpha network install DVD


Seems to me that initial versions of the software used for F16 installation media were OK, but then, an issue was introduced that made it to installation of F17, and updates of F16.

F16 data mined from the system:

kernel-3.2.6-3.fc16.x86_64
xorg-x11-server-1.11.4-1.fc16.x86_64

Comment 26 Fedora End Of Life 2012-08-07 15:38:10 UTC 
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. 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 '15' 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 15 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:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 27 Andrew 2012-08-07 17:12:59 UTC 
I've played with KDE visual effects settings and this issue is absent for a couple of months. However it might be unrelated.
