Description carbonfreeze 2010-10-13 13:10:10 UTC 
Ubuntu 10.10 x64
Thinkpad T61
01:00.0 VGA compatible controller: nVidia Corporation G84M [Quadro NVS 140M] (rev a1) (prog-if 00 [VGA controller])

Xorg locks up somewhat randomly. I primarily notice this issue when switching virtual desktops in KDE, or switching to a GTK application. Maximum login time before triggering this issue can be anywhere from 30m to a day. When the lockup occurs, I noted the following things:

Anything that was happening on the screen stops (animations, clock, etc)
Mouse can still be moved
System does not react to keyboard input (cannot switch vt, have not tried sysrq)
Can login to system via ssh, but attempting to restart X appears to result in a hard lock of the system (network goes down, no disk activity)
Occurs with KDM and GDM, in either KDE or XFCE
Occurs on AC or Battery power
Occurs on external monitor (dsub) or internal LCD
Occurs when switching virtual desktops, unlocking 2d screensaver, switching to or clicking buttons in GNUcash and a few other cases


Nouveau packages installed from xorg-edgers (git20101012) and earlier effected.

Proprietary driver not effected by issue, however the system seems to slow down a bit where I would experience lockups with nouveau (there is a noticeable 2d draw latency).

When starting the system with nouveau.noaccel=1, I have been unable to reproduce the lockup. Normally without the entry I am unable to maintain an uptime over 8 hours, now running with nouveau.noaccel=1 I have been running 3 days without triggering the issue.

Xorg log from lockup (external monitor plug)

First lockup of the day, happened a few seconds after I plugged in an external monitor. Note that the system had just resumed from suspend ~5 minutes before. Maybe not the same bug as reported, but the same symptoms.

From dmesg:
[drm] nouveau 0000:01:00.0: 0x0FD9: parsing clock script 0
Comment 3 nox 2010-11-26 12:52:40 UTC 
notebook: Lenovo Thinkpad r61 with NVIDIA Quadro nvs 140m G84m
system: Debian squeeze/sid
kernel: 2.6.35-amd64
nouveau version (from Debian experimental repos): xserver-xorg-video-nouveau v.1:0.0.16+git20100825+390f1c8-1

I suffer the same issue, X locks randomly during KDE sessions. Keyboard and input system not responding.

I noticed this on dmesg when the problem occurs:
[13627.748754] [drm] nouveau 0000:01:00.0: PFIFO_DMA_PUSHER - Ch 2

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
