Description Paolo Prandini 2005-01-23 14:14:46 UTC

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)

Description of problem:
Running Blender 2.36 in both static and non static version, regardless
of X harware acceleration (dri on/off) on Fedora Core 3 is not
possible due to crashes. The same was not happening on Fedora Core 2. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Download Blender from blender site both static and non static version
2. Download demo_loop.zip file from blender site 
3. expand blender in two diferent directories using tar -zxvf 
4. expand demo_loop.zip into a directory of your choice
5. Run blender
6. open file airship_Penner.blend (should be in demos directory if you
did right on point 4.
7. Blender crashes after a short while, as long as auto rendering of
animation begins 

Actual Results:  Blender crashes when using both blender version
(static no HW-OpenGL) and non static (HW-OpenGl)

Expected Results:  As in Fedora Core 2, all works like a charm.
Animation is rendered and automatically it moves to the next file and
so on.

Additional info:

The HW :
P4HT 2.6Ghz, 512MB Ram, ATI Radeon 9200 128MB RAM.

Working FC2 Setup :
Kernel 2.6.10-1.9_FC2smp

FC3 Setup : 

Kernel : kernel-smp-2.6.10-1.741_FC3.i686.rpm

Is there anything in dmesg?

If Blender itself is crashing, then the problem is most likely a bug in
Blender itself, or a bug in libraries that Blender links to.  You will need
to file a Blender bug report to the authors of Blender, indicating the
details of your problem, etc. and they will then be able to investigate
the problem and debug their source code.  If they determine the problem is
a bug in an X11 library which is included in the X.Org X11 distribution,
then a bug report should be filed in the X.Org bugzilla.

http://bugs.freedesktop.org "xorg" component.

If the problem is in Blender itself, then they will probably address the
issue in a future release of Blender.  If the problem turns out to be
a legitimate bug in X.Org libraries, once X.Org developers investigate
the issue, it will probably be fixed in a future X.Org release.

Once you've filed your bug report to Blender and/or X.Org, you can paste
the bug report URLs here and we will periodically review them.  If X.Org
developers determine there is a flaw in X.Org causing this issue, and
produce a patch to fix it, we will then review the patch for consideration
in future Fedora Core xorg-x11 builds.

Hope this helps.

Setting status to "NEEDINFO" and awaiting upstream bug report URL's for
tracking purposes.

Comment 4 Paolo Prandini 2005-01-24 07:40:32 UTC

I will look at dmesg and do as instructed.
Is there any other log that can be useful to look at?

 - How can I completely disable HW GL acceleration apart from removing dri from

Comment 5 Paolo Prandini 2005-01-24 08:43:31 UTC

Dmesg reports nothing
Launching Blender in a terminal window I can see the exit message as 'segfault'.
Opened bug# 2170 on blender bugtracker.

Please provide the full http URL to the blender bug report, as the
above link points to Red Hat bugzilla.

Comment 7 Paolo Prandini 2005-02-13 21:47:22 UTC

Blender works fine if variable SDL_AUDIODRIVER=dma
is set prior to blender launch.
This was not necessary in FC2.
So it seems is DMA and audio...

Hope it helps

Comment 8 Mike A. Harris 2005-03-02 03:35:57 UTC
From the best I can tell from this bug report, it is "blender" that
is crashing, and NOT the X server.  And this is somehow related
to how SDL audio is configured.  This sounds more like a kernel
driver issue, or a bug in SDL itself, and increasingly does not
sound at all like an Xorg bug/problem.

Reassigning to SDL component, to see if the sdl package
maintainer is familiar with this issue.  If it isn't an sdl
issue, I'd recommend reassigning it to the kernel component.

Thanks for your time
I appreciate that.

Comment 10 Thomas Woerner 2006-01-27 13:51:07 UTC
Can you please have a look at the latest FC-4 update package of SDL (1.2.8-4)?

This version is using alsa output as default.

Is it solving your problems for FC-3, too?

Comment 11 John Thacker 2006-05-06 12:27:03 UTC
Closing due to lack of response by reporter.
Note that FC3 is now the responsibility of Fedora Legacy, and this
does not appear to be a security bug.  If the bug persists in FC4
or FC5, please reopen it.
