Hi.

Not sure whether this is related to the similar bugs I've reported recently,
neither whether it's related to the 2D or 3D part... so please be patient
with
my report ;)

It happens on a Debian sid machine with Linux 3.0 and:
$ apt-cache show xserver-xorg | grep Version
Version: 1:7.6+7
apt-cache show xserver-xorg-core | grep Version
Version: 2:1.10.3-1
apt-cache show xserver-xorg-video-nouveau | grep Version
Version: 1:0.0.16+git20110411+8378443-1+b1
apt-cache show libdrm-nouveau1a | grep Version
Version: 2.4.26-1
apt-cache show libgl1-mesa-dri-experimental | grep Version
Version: 7.10.3-4

The GPU is a G94 [GeForce 9600 GT].
I have two screens attached, but  not via Xinerama or the like, but two
separate X screens.

When I play a video on the 2nd screen it quickly happens that nouveau/X
freezes,... keyboard no longer works, switching to console neither,.. mouse
works (but as everything is frozen,.. this is of little use.
It seems that the system in the back continues to run (see the SysRq messages
that are printed in the log).
SysRq also works (well at least +b).

The funny thing is, that is happens only very rarely (but also sometimes) that
the system freezes when I play a video on the 1st screen.

(btw: I used mplayer from Debian Multimedia)

Sometimes (but rarely) I see it already coming (the freeze),.. then strange
graphic erros appear on the screen (and the system has not yet frozen),... even
more rarely I can than trigger a clean shutdown.


Cheers,
Chris.

Hi Christoph

Looking in your log many(most) of the ERROR messages are 3D/GL related

On top of that please note that there has been a bug in kernel 2.6.39 that
causes the system to hang when Xv is used in conjunction with 3D(GL
app/game/compositing window manager)

Can you try the following
1. Remove libgl1-mesa-dri-experimental and/or update your kernel to 3.0

Note in general (with nouveau) it's recommended to try the latest (git)
version
of the following

1, kernel [1]
2. libdrm -- in your case it's not necessary
3. xf86-video-nouveau
4. optional mesa

Can you give the suggestion(s) a try (I highly recommend removing
mesa-experimental just to narrow down the issue)

Cheers
Emil

Hi.

Well disabling 3D makes the whole thing quit boring, right? ;)
And isn't it shipped as more or less "stable" now anyway?


Nevertheless, the problem persists, but few news:
I tried just before with Linux 3.0.0 (upgrading that system to the most recent
versions is a bit painful).

Things have improved a bit:
The system no longer freezes forever, it recovers after some time (2-3 minutes)
and continues to work "flawlessly".

Also this seems to be no longer specially triggered by watching video but
rather by e.g. switching the virtual desktop (and the then ongoing compiz 3D
animations).

During the freeze, e.g. the sound continues to work. But mouse/keboard are
dead.

Could you retest with a fresh kernel/xf86-video-nouveau/mesa?

No response to re-test request in over a month. Closing as invalid.
