Nouveau - Mar 2012 - [Bug 47288] New: System hangs with GeForce 6150SE nForce 430

https://bugs.freedesktop.org/show_bug.cgi?id=47288

             Bug #: 47288
           Summary: System hangs with GeForce 6150SE nForce 430
    Classification: Unclassified
           Product: xorg
           Version: 7.6 (2010.12)
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: fschaefer.oss at googlemail.com
         QAContact: xorg-team at lists.x.org


My system (GeForce 6150SE nForce 430) hangs up from time to time under KDE
4.7.4. All I can do then is to move the mouse pointer.
Clicks have no effect and I can not switch to the console. I even can't shut
down the system pressing the power button.
It seems I can trigger this by increasing the workload, e.g when
maximizing/minimizing lots of windows.

Xorg.0.log shows the following messages (full file attached):
...

The kernel log shows the following suspicious messages:
...
[  765.361432] [drm] nouveau 0000:00:0d.0: fail pre-validate sync
[  765.361442] [drm] nouveau 0000:00:0d.0: validate vram_list
[  765.361452] [drm] nouveau 0000:00:0d.0: validate: -16
...

I'm using openSUSE 12.1 (kernel 3.1.9, Xorg 7.6). I also tried kernel
3.3.0-rc7.

Please install drm-nouveau-kmp-{flavor}, libllvm, libdrm, Mesa and
xorg-x11-driver-video from home:jobermayr together with kernel from
openSUSE:12.1:Update. Only bugs present in them are valid.

Ok, I will try that...
The kernel is already up-to-date (3.1.9).

Please confirm that the following changes are correct:

drm-nouveau-kmp-desktop: currently not installed (?!) =>
20120309.0650_k3.1.9_1.4-1.1
libllvm: currently not installed (?!) => 3.0.99.svn20120312
libdrm: 2.4.26-15.1.2 => no update available. Do you mean libdrm2
(2.4.99git20120310.1721-2.1) ?
Mesa: 7.11 => 8.0.99
xorg-x11-driver-video: 7.6 => 7.6.99

What about xorg-x11-driver-nouveau ?

seems similar to mine, not sure if it is the same problem, bug 48434.

Suggest, login with ssh from another machine (I used to use android phone) and
run as root "killall -s 9 -I xorg", this kill x and restart gnome
display
manager (gdm3) and then I can login again. With this method you avoid to reset
and damage your filesystem.

Still happens (even more often than before) with

kernel 3.4.5
Mesa 8.0.99.git20120707
libdrm 2.4.99.git20120706
libllvm 3.1.99.svn20120708


The kernel logs now show much more of these lines:

[drm] nouveau 0000:00:0d.0: fail pre-validate sync
[drm] nouveau 0000:00:0d.0: validate vram_list
[drm] nouveau 0000:00:0d.0: validate: -16
[drm] nouveau 0000:00:0d.0: cal_space: -16
[drm] nouveau 0000:00:0d.0: cal_space: -16
[drm] nouveau 0000:00:0d.0: cal_space: -16
...


This bug is really easy to trigger, all you need to do is to enable KDE
standard desktop effects => lockup in less than 5 minutes !

Hello,

I'm using the same hardware (Geforce 6150/nForce 430) and experiencing the
same
problem since months, at least since GNOME 3.0 release with compositing
enabled, and then with KDE 4.7 with compositing enabled also.

Currently I'm running Fedora 17 with these:
kernel 3.4.6-2
libdrm 2.4.33
mesa-dri-drivers 8.0.3
xorg-x11-drv-nouveau 37.20120306gitf5d1cd2.fc17

The problem seems to occur randomly, but often while typing text in a Firefox
window.

Following the Debugging documentation, I have been able to log with SSH and use
gdb. From here, I can see that Xorg does not crash, the display and input just
seem "frozen".

Xorg log gives the following backtrace:

existing events are processed.

I don't know if what I did with "gdb" was the correct way but the
output next.

This basically means that your card has hung. The EQ overflowing thing is just
X noticing that its event queue is filling up because the DDX is stuck. The
kernel messages indicate various validation/space/vram errors. Does this still
happen on the latest kernels? If so, could you provide an updated log that
includes the part that happens when the hang happens?

Since the desktop efects are probably GL/Mesa based you can also try upgrading
Mesa and libdrm
