Created attachment 85813
  --> https://bugs.freedesktop.org/attachment.cgi?id=85813&action=edit
Screenshot taken with `import` after opening a new tab in Iceweasel 17.0.8

Using Debian Wheezy with

    linux-image-3.2.0-4-686-pae 3.2.46-1+deb7u1
    xserver-xorg-video-nouveau 1:1.0.1-5
    libglu1-mesa:i386 8.0.5-4+deb7u2
    libdrm2                                2.4.40-1~deb7u2
    libudev0                               175-7.2
    xserver-xorg-core [xorg-video-abi-12]  2:1.12.4-6

sometimes there is an image corruption where some areas are garbled with other
colors. See the attached screenshot taken with `import` from the ImageMagick
suite. (What is that type of corruption called?)

The obfuscation was done with the following command.

    $ convert 20130909-Debian_Wheezy-nouveau-corruption.png -draw "rectangle
231,165 1703,953" 20130909-Debian_Wheezy-nouveau-corruption--obfuscated.png

This issue happened five times and I do not know how to force it. Three of
these five times it happened after resuming from suspend to RAM. Additionally
after these corruption start, the system is going to freeze after some time.
There are no error messages in `/var/log/syslog`, `/var/log/messages`,
`/var/log/Xorg.0.log` and `~/.xsession-errors`.

Please tell me, what else you need for debugging.

Please see if this still happens with the most recent software. If that's not
an option for you, feel free to file a bug with debian and close this one. If
it still happens with the most recent software, please take a look at
http://nouveau.freedesktop.org/wiki/Bugs/ to see what information is needed.

Today it happened again¹.

1. Some more information about the system:

        $ lspci -s 4:00
        04:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 8400
GS] (rev a1)

I have another system with an integrated Nvidia device, where I have not been
able to reproduce this.

        $ lspci -s 2:00
02:00.0 VGA compatible controller: NVIDIA Corporation C77 [GeForce 8200] (rev
a2)

2. The same corruptions started some time after startup (no suspend in
between). After some time, I closed Iceweasel/Firefox and the system froze. I
just pressed the reset button and the corruption was right there the next
start. So it might have to do something with the card setup. Then it froze
pretty quickly (after five minutes) without even starting Iceweasel/Firefox and
just awesome WM and uxrvt terminals running. Switching the power supply and
then starting again the corruption was gone and I could not reproduce it again
today.

3. This is a hard freeze, meaning I am not able to ping the machine when it is
frozen.

4. I checked again and the log files do not contain anything before the crash
related to Nouveau or the graphics stack.

5. I am going to try Linux 3.10 from Debian Backports [1], though was not the
Linux Nouveau module rewritten in Linux 3.7 [2], so that this is not going to
point to the problem in Linux 3.2 (with DRM from 3.4.47 [3])?

Also make sure that you have an up-to-date xf86-video-nouveau, and mesa if
you're using some sort of opengl-based compositor. I don't think there's any
interest to maintain backports of fixes for nouveau (by the nouveau dev
community), so if you'd like to see it fixed in Debian, you'll need to talk to
Debian people.

Yes, I am still able to reproduce this with Debian Jessie/testing, which
currently has Linux kernel 3.19.x and `xserver-xorg-video-nouveau` 1:1.0.11-1.

Suddenly the corruptions start on the left side of the monitor and then I can
see how slow the window of uxterm is rendered line by line (takes maybe two
seconds). If I do not shut the system down, it’ll eventually freeze.

Are there any messages in dmesg when this happens? I assume this is still with
the G98?

What environment do you use? Gnome? KDE? Redirecting compositor which uses GL?

This is now with Debian 8.1 (Jessie/stable) and Linux 4.1.1.

> Are there any messages in dmesg when this happens?

Normally there are no messages. In a few times, the following message can be
seen.

    [  663.478750] do_IRQ: 1.160 No irq handler for vector (irq -1)

> I assume this is still with the G98?

Indeed, it’s still with the same card.

The awesome WM 3.4.15 [1] (no compositing as far as I know) is started with

I installed Linux 4.2-1~exp1 (linux-image-4.2.0-trunk-686-pae) and, today, the
issue happened after using the system for 20 minutes without any suspend/resume
cycle in between.
