Created attachment 29320 [details] Xorg configuration file, also tried turning backingstore off With compositing enabled the XServer crashes frequently and randomly on my machine. Especially desktop effects (from KDE 4.3 or compiz-fusion) cause the crash. My setup: - HP nx6125, 1.2 GB Ram - Radeon XPress 200M - Linux 2.6.30.1 (in-kernel radeon DRM module) - XServer 1.5.3, libdrm 2.4.12, mesa 7.5, xf86-video-ati 6.12.2 Backtrace: (gdb) cont Continuing. Program received signal SIGABRT, Aborted.

Debug symbols would help in backtrace. I don't know why this backtrace is cut but it would help if you could get backtrace to show what is calling the _mesa_reference_texobj. If there is no easy way to get ful lbacktrace then running X with RADEON_DEBUG=all environment variable set might give useful info what is going wrong. But this will produce large log file which you might have to compress because of limit in attachment sizes. This output goes to [gk]dm log file or to console (if using startx).
I don't know, but for some reasons the only information I can get out of the backtrace is this "_mesa_reference_texobj () from /usr/lib/dri/r300_dri.so" thing. I did also upgrade to XServer 1.6.3.901 and 7.5.1, but the problem still persists. I have attached my compressed kdm.log with RADEON_DEBUG=all.

The classic r300 driver has been abandoned long ago. It was replaced by the Gallium driver r300g. If you have issues with r300g please file a new bug report with component Drivers/Gallium/r300 Thanks.
