> does glxgears work on your setup? I didn't test glxgears and am actually before this commit. Will try glxgears at my next bisecting round (for another bug). > what gpu exactly do you have this bug with? Sapphire Radeon HD 6950 (the one with dual BIOS and dual fans) with unlocked shaders (factory BIOS, not modded by me) and most likely with the locked BIOS, too, but there I can't tell really tell cause the GPU crashes right after compiz starts. > kernel radeon says smth like this I reported that, too. In fact I reported a few other bugs that seem all to be caused by this (and other) commits: https://bugs.freedesktop.org/show_bug.cgi?id=58660 https://bugs.freedesktop.org/show_bug.cgi?id=58661 https://bugs.freedesktop.org/show_bug.cgi?id=58667 Help with bisecting is always welcome. :)
