I have an ATI radeon IGP 320M (mobility U1) card which works well with radeon driver. 2d and 3d accelerations are working. But there is a problem with Blender since a update on my debian SID of libgl1-mesa-dri and libgl1-mesa-glx from 6.5.1 to 6.5.2. I use dri driver (not fglrx). There is no error/warning message in log. I have had a similar problem for some years : https://bugs.freedesktop.org/show_bug.cgi?id=5601 My version of blender is 2.42a.

I'm having the same problem with the ati driver and a ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500] card. I'm using the same versions as Aurelien in Debian Sid.
With the 7.0.1 version, blender crash : guessing 'blender-bin' == '/usr/bin/blender-bin' Compiled with Python version 2.4.4. Checking for installed Python... got it! /usr/bin/blender: line 46: 8958 Segmentation fault blender-bin "$@"
If blender still segfaults with latest drm and Mesa, could you produce a backtrace, Aurelien?
The bug is different between 6.5.2 and 7.0.1 release. So I have opened a new bug report (https://bugs.freedesktop.org/show_bug.cgi?id=12164) which is solved. I think we can close this bug report. Many thanks
Closing this bug reopen if you still experience same issue with recent mesa.
