X crashlog

I got hit by the same bug... Xorg crashes when closing glxgears (simply press X and expect X to crash sometimes...). GPU is HD 6520g.

I built the driver in ubuntu (13.04, amd64, KDE/LXDE) this way (skip if you don't care, I'm posting this to show you how I did it, to be sure it's done correctly, and finally, for my own record...):

I took the instructions from the buildlog in the PPA: https://launchpadlibrarian.net/141183209/buildlog_ubuntu-raring-amd64.xserver-xorg-video-ati_1%3A7.1.99%2Bgit20130531.bd2557ea-0ubuntu0sarvatt~raring_UPLOADING.txt.gz

mkdir temp && cd temp && apt-get source xserver-xorg-video-ati=1:7.1.99+git20130531.bd2557ea-0ubuntu0sarvatt~raring
sudo apt-get -s build-dep xserver-xorg-video-ati
cd xserver-xorg-video-ati-7.1.99+git20130531.bd2557ea/
(edited src/radeon_dri2.c, patched manually)
/usr/bin/fakeroot debian/rules clean
debian/rules build-arch
/usr/bin/fakeroot debian/rules binary-arch

last message I got is: "dpkg-deb: building package `xserver-xorg-video-radeon-dbg' in `../xserver-xorg-video-radeon-dbg_7.1.99+git20130531.bd2557ea-0ubuntu0sarvatt~raring_amd64.deb'."

so, I installed that package... and I got the crash showed in the logs, and then the X server restarted.
