Xorg log file
Description of problem:
Shuttle SB51G (SIS 651 chipset), NVIdia Geforce 6200 AGP will cause the X session to hang with the X process taking 100% CPU after a random (short) period of time.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log in X
2. Start a few application (usually gnome-terminal, firefox)
The X session hangs, cannot switch to console. Need to ssh to the system and kill -9 the X process to recover
The X session does not hang.
gdb on the X process shows the following backtrace:
#0 0x00560770 in nouveau_fence_flush () from /usr/lib/libdrm_nouveau.so.1
#1 0x0056053a in nouveau_fence_wait () from /usr/lib/libdrm_nouveau.so.1

#16 0x08086807 in Dispatch ()

There are other current BZ about X+Nouveau taking 100% CPU but the backtrace differs from the above.
How do you fare if you boot with nouveau.noagp=1 on the kernel commandline?

Yeap, that made the trick, it seems stable with that option. Thanks!

Could we get output of the command

Thank you very much

Forget about this, I forget we don't provide nouveau_dri.so currently.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
I think I'm seeing the same with:
05:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600] (rev a2)
Not much action here. Do we need to file upstream?
Your issue may not be the same as the OP's, but Ben would know.
Reporting upstream certainly couldn't hurt, but Ben is one of the main upstream nouveau developers, and he is working on all bugs filed in RH Bugzilla, just there's quite a few and he can't fix them all at once :)

Yes, agree. Actually I thought the issue was fixed as the problem does not occur anymore in my case (even w/out the "nouveau.noagp=1" option).
As far as I can tell, the original issue has been fixed.
Just to confirm, Olivier - you're on F11 final with updates, or Rawhide?

That's interesting to note. If it's rawhide I have noticed on a couple of cards I have that AGP seems more stable, the reason is unknown though. I still have one card where I need to use it however. Anyway, I'll wait for Oliver to confirm F11 or rawhide and close appropriately!
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command
yum upgrade --enablerepo='*-updates-testing'
Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .
Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.
If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
[This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
Oliver, this is a reminder that there is a question in Comment #11 awaiting your answer. :)

Could you please reply to the previous question? If you won't reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
[Note please, that this is machine generated comment for large amount of bugs; due to some technical issues, it is possible we've missed some of the responses -- it is happens, please, just a make a comment about that; that we will see. Thank you]

Oh sorry I missed that one!
That was on F11 final with updates. But the trick from comment 1 fixed it, I have not retried since then.
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
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 prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 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 please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
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:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
Thank you for reporting this bug and we are sorry it could not be fixed.
