Bug #: 42297 Summary: [r600g] Segfaults and failed assertions with piglit test fbo-generatemipmap-formats Classification: Unclassified Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: tdroste@gmx.de

Below are backtraces from segfaults and failed assertions while running the piglit test fbo-generatemipmap-formats. I tried it with and without R600_TILING=on.

piglit: from git and updated+rebuilt today. Mesa: 2.1 Mesa 7.12-devel (git-4fc9a98) Driver: r600g Kernel: 3.0 Hardware: Evergreen (Juniper)
