Same problem here with a Thinkpad R51 laptop, Radeon Mobility 7500 (M7 LW), Debian Lenny. Looking at the stack trace, it seems a problem exists with VBOs, maybe they are not yet correctly implemented in the driver. However, there is not a way for me to disable them in Blender.

My stack trace seems to show that a recursive bug is overflowing the stack:

Alberto, could you try a debug build of Mesa to get a stack trace with function arguments?

If you can provide detailed instructions on how to reproduce this I'll give it a try. I don't know how to use Blender otherwise.

Hello Brian, thank you for your help. Here I send the stack trace with arguments.

The way to reproduce the crash in Blender is easy:

1-Open Blender
2-Hit the space bar. A menu will be shown. Select from the menu: Add->Mesh->UVSphere. Accept the defaults clicking on "OK".
3-Now you are on "edit mode". Hit TAB to "exit edit mode"...
4-Crash

Here are the last frames of the stack trace:

Created an attachment (id=11687)
emit debug info in t_dd_tritmp.h

I don't have an r200 to test with and I haven't been able to make blender crash with software rendering (Xlib driver).

It looks like you've found crashes into two totally different places. Can you explain what you're doing differently in those two cases?

Can you apply this patch to src/mesa/tnl_dd/t_dd_tritmp.h, recompile your r200 driver, then re-run blender? If you hit the problem in triangle_twoside() it should print some debug info that might help me.

This patch works perfectly ! Blender doesn't crash.

I will use blender during one week to see if this patch is stable. But I think problem is solved. I will go back in one week to close or not this bug.

In any case, many thanks !

I think a change that I made to how _TriangleCaps is computed (last December) is the root cause here. I didn't realize _TriangleCaps was sometimes used before state validation (such as in ChooseRenderState()). So when I moved all the _TriangleCaps computation to state validation time it resulted in stale flags being used.

I'm working on a patch to undo that change (plus comments to document this mechanism).

Otherwise, look for a 7.0.2 release candidate in the next day or two.

After the crash, the stack is: (should I file another bug report for this one? It worked well with 6.5.1 and 6.5.2, the crashes started from 6.5.3)

#24

Download full text (3.2 KiB)

hi,

I am having issues with blender 2.44 (gutsy) using the radeon dri drivers.

The card is a sapphire radeon 9250 with 128MB.
lspci reports the following:
01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (rev 01)

Blender shows often (but not always) rendering errors while modelling.
Moreover if i switch to camera (0/ins key on the numeric pad) the center of the view is black.
Finally it tends to crash if i try to move away form camera mode (hitting key 7 or key 3 on the numeric pad).
The crash is reproduceable easily.
Below the output of gdb:

Backtrace. Edit (5.4 KiB, text/plain)

I can confirm this one. This must be something about some new drivers, because blender used to work fine on this machine.

Hardware:
Card: ATI Technologies Inc RV280 [Radeon 9200 SE] (rev 01)
Processor: AMD Athlon(tm) 64 Processor 2800+
Chipset: nVidia Corporation nForce3 250Gb
(There are some more similar reports in different places about all with radeons 9200 & 9250.)

Software:
Ubuntu 7.10, x64.
OpenGL renderer string: Mesa DRI R200 20060602 AGP 8x TCL
OpenGL version string: 1.3 Mesa 7.0.1
Blender 2.44 and 2.45 with Python 2.5.1.

A discussion on freedesktop.org pointing which mesa versions work and which don't:
http://<email address hidden>/msg32485.html
(You can find a patch there, but only solving the crash not the black square, not really helpful.)

Attaching a screenshot and a backtrace.

Can you possibly try the latest code from Mesa git on the mesa_7_0_branch branch? I fixed a two-sided lighting bug a couple weeks ago that might solve this.

I confirm the bug seems to be fixed in mesa_7_0_branch (checked out 4th january).

I had exactly the same crash as Sean in comment #23 (same stack trace) on a fresh Fedora 8 installation with an intel i865 chipset (DRI "driver" i915_dri.so).

I recompiled the latest sources from mesa_7_0_branch, and Blender started like a charm. :)

Ouch, that was 189 MB for nothing then :) Well, it can still prove useful.

From looking closer at the backtrace, we can see that the stack is clearly messed up, since it has addresses like 0x00000001 and 0xffffffff. If this crash is reproducible, it should be possible to define a breakpoint (for instance on r200UpdateTextureState?) and enable it just before making it crash. From there on, see how far you can get with stepping or refining breakpoints until you get a backtrace while it still uncorrupted. I admit this can be quite an exercise in gdb... A good introduction is on http://www-128.ibm.com/developerworks/library/l-gdb/

If this is the same issue as in the upstream bug, it should be fixed in Hardy by now (mesa 7.0.2-3ubuntu1). Please test, for instance with the alpha 3 release due this week.

I saw you have a PPA (https://launchpad.net/~tormodvolden/+archive)
I may check installing your packages on gutsy, if you think it would be useful.

Hi, I run opensuse 10.3 and have similar problems with blender and /usr/lib/dri/r200_dri.so

Mesa-7.0.1
ATI Mobility radeon 9200,
My Xorg.conf file contains the following lines in the "Device" section:
  BoardName "RV280 5c61"
  Driver "radeon"
  Identifier "Device[0]"
  VendorName "ATI"

Both Blender 2.44 and Blender 2.45 give me segmentation fault after a few minutes of use.
With gdb blender I get the below outcome. Any idea how to solve it? Should I try to install Mesa 7.0.2 ?

Thank you very much for your great support!!
I found that mesa-7.0.3 is available as RPM for opensuse 10.3 from:

http://download.opensuse.org/repositories/home:/zwabel/openSUSE_10.3/i586/

or searching for mesa in: http://software.opensuse.org/search

After installing it, all the problems with blender solved.
Thank you once again.
