with 7.1 things are even worse .. i reinstalled the distro from scratch. i installed 7.0 ( latest stable ) that didnt work .. so i went to 7.1 and then i experienced complete server crashes.Cant even make a core dump file. so .. I added option aiglx off in the xorg conf and the crashes leave me with a froxen screen but at least i can get out of X kill the application and come back in and pick up where i left off . Still cant produce any core dumps though . I really could use some help here. Hello, same problem here, with a Gentoo x86 system
Using
* xorg-7.0
* mesa-6.4 (i also tried mesa-6.5, with same results)
on a 3Dfx Voodoo3 2000
I'm trying to run Vavoom Engine (www.vavoom-engine.com)
This is a backtrace:

I hope it helps :)
This one was easy. As we can see, _mesa_DeleteTextures( ) calls _mesa_free_texmemory( ), which expects texImage->Data to be allocated using _mesa_align_malloc( ). _mesa_align_free( ) expects texImage->Data to be prepended by one word with actual address to pass to real free( ), but it's not, because tdfx driver uses stock _mesa_malloc( ) without the alignment part. The bytes before texImage->Data are garbage, so there's no way it could not crash. I'll attach a patch in a moment, after I do some more testing (I mean play QuakeForge, at last). Oh, my card is PCI Voodoo3 2000. The bug happens in Mesa 6.4.2 (from FC5) and 6.5 (from AIGLX for FC5, both rebuilt for Xorg 7.0 with tdfx_dri.so enabled). The patch will be against 6.5, because that's what I ended up with. Created attachment 6640 [details] [review] The patch for Mesa 6.5 and tdfx_dri crash Works for me. Ouch, all my work for nothing, this was fixed in Mesa CVS long time ago: http://webcvs.freedesktop.org/mesa/Mesa/src/mesa/drivers/dri/tdfx/tdfx_tex.c?r1=1.32&r2=1.33&diff_format=u (as ajax told me on irc) guess we needed to ask the right person :) unfortunately .. i have gone for a newer card since i reported the bug.Still not fixed in gentoo though. So Thank you for the solution/fix. It's very appreciated. Richard Hebert *** Bug 8034 has been marked as a duplicate of this bug. *** I have to say for future reference that DRI 3D with tdfx driver has been broken for the following releases of UBUNTU:
Breezy
Dapper
Edgy
Feisty
And that it works again (first time since Hoary) whith Gutsy (Vodoo 3/banshee).
Also the MGA (Matrox G400) driver seems to work again (in some of the past ubuntu releases the image was corrupted in 3D).
The working driver combo information for Gutsy is as follows:
DDX:
(II) Module tdfx: vendor="X.Org Foundation"
compiled for 7.2.0, module version = 1.3.0
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 1.1
DRM:
(II) TDFX(0): [drm] loaded kernel module for "tdfx" driver
(II) TDFX(0): [drm] DRM interface version 1.3
DRI/MESA:
OpenGL renderer string: Mesa DRI VoodooBanshee 20061113 x86/MMX/SSE
OpenGL version string: 1.2 Mesa 7.0.1
