--- Comment #4 from dri tester writemeanddie@hotmail.com 2011-05-09 06:22:56 PDT --- But if I downgrade to mesa 7.10.2, I am still using llvm 2.9 and the crackberg screensaver works correctly, so that would point to mesa-git being the problem for me. I cannot compile mesa-git without llvm as the build process halts and complains that r300 gallium requires llvm to build. There are three gentoo patches that get applied on top of the mesa 7.10.2-r1 build, I haven't looked at what they do yet.

I have some problem, and i have ATI RS482 too, but i think it was the fault llvm, with out llvm or < 2.9 , all woks fine, with llvm > 2.8 openarena, urbanterror and some xscreensaver segfault. see https://bugs.freedesktop.org/show_bug.cgi?id=36738 I make backtrace with crackberg.
