with 2.6.29 If use EXA ,I also get these three error lines but if use UXA, only the front buffer error occurs > AIUI there are tiling fixes queued for upcoming kernels.

Yes,I followed this ,and built a custom 2.6.30-rc3 kernel from git the errors disappear.but still UXA is much faster than EXA here's my simple benchmark result: x11perf -aa10text glxgears EXA: 459000.0/sec 45FPS UXA : 654000.0/sec 430FPS -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
