Attachment described below.

Distro: Ubuntu Jaunty development version

Attached are three test cases containing the configuration used for each one and the corresponding logs.

In cases 411pm and 426pm, the video card will crash with corruption and xorg will exit with a GPU lockup message.  In 431pm, the card starts using NoAccel=true.

In all cases, Xorg was started with:

"sudo Xorg -logverbose 6 :0"

over ssh from another machine.  I couldn't find any backtraces from gdb since Xorg exited softly with code 1 (I think that #), no crash.

Comment 2 Andy Matteson 2009-03-20 15:16:47 UTC 
To be clear, xorg is crashing after I do DISPLAY=:0 xterm and type a few commands in xterm to cause a few painting commands.

It exits with this message in the Xorg log:


Fatal server error:
Detected GPU lockup

Comment 3 Andy Matteson 2009-03-20 15:31:28 UTC 
Also very important: I think that accelerated EXA USED TO WORK on my card about a few months back!  (I am not sure about this.  I never messed with a NoAccel parameter to my knowledge and I'm not sure of the default back then or when it was working.)  I do recall being able to play videos and my desktop was definitely not this slow.
Comment 4 Andy Matteson 2009-03-20 22:30:40 UTC 
Very sure it's related to this bug: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nv/+bug/62230

and

http://www.nvnews.net/vbulletin/showthread.php?t=31858&pp=15&highlight=loop&page=27

Older version of nouveau gives more details about the crash and more fifo info.

Comment 8 Andy Matteson 2009-03-21 02:21:42 UTC 
I don't know that EXA ever worked on this card, specifically actually.  I tried different revisions of nouveau all the way back to when they just added ctx voodoo for the nv47 (my card), and nothing worked right with noaccel=false.  With noaccel=true, the newer nouveaus work much better too.

I attached error logs of a 2008-01-xx nouveau that exhibited the same symptoms as the most recent nouveau (corruption---->crashing later), and gave more fifo info.

It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
