Bug ID: 91881 Summary: regression: GPU lockups since mesa-11.0.0_rc1 on RV620 (r600) driver Product: Mesa Version: 11.0 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: markus.gapp@pr-link.at QA Contact: dri-devel@lists.freedesktop.org

Hi

On a Gentoo System I experience repeated random segfaults of mostly kde x11 applications and xorg freezes since updrading mesa from 10.x.y to 11.0.0_rc[12].

mesa was compiled with (gentoo use flags): classic dri3 egl gallium gbm gles1 gles2 nptl osmesa udev xa xvmc

llvm was compiled with (gentoo use flags): clang libffi ncurses python static-analyzer xml

llvm 3.7.0 & 3.6.2 (no difference) kernel 4.2.0 & 4.1.6 (no difference) librm 2.6.64

xorg log is silent.
