And that should not have regressed. Can you please, grab an intel_reg_dumper of the working setup and the lost-sync setup, and include a drm.debug=0xe dmesg (i.e. add drm.debug=0xe to your boot commandline)? > With 2.6.37-rc6 and mesa 7.10 with hardware acceleration turned off in wine- > > Dec 18 18:01:50 joker4 yum[5244]: Updated: mesa-libGL-7.10-0.17.fc15.x86_64 > Dec 18 18:01:52 joker4 yum[5244]: Updated: mesa-libGL-7.10-0.17.fc15.i686 > Dec 18 18:01:54 joker4 yum[5244]: Updated: mesa-libGLU-7.10-0.17.fc15.x86_64 > Dec 18 18:02:02 joker4 yum[5244]: Updated: mesa-dri-drivers-7.10-0.17.fc15.x86_6 > 4 > Dec 18 18:02:03 joker4 yum[5244]: Updated: mesa-libGLU-7.10-0.17.fc15.i686 > Dec 18 18:02:11 joker4 yum[5244]: Updated: mesa-dri-drivers-7.10-0.17.fc15.i686 Good, those drivers are recent enough that I should be able to use the error state to find the broken code. -Chris -- Chris Wilson, Intel Open Source Technology Centre -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
