           Summary: Nouveau 3D driver: nv50_pc_emit.c:863 assertion error
                    kills Compiz
           Product: Mesa
           Version: 7.10
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: sense-GeWIH/nMZzLQT0dZR+AlfA@public.gmane.org


When you use the experimental Gallium3D driver of Nouveau to enable DRI, Compiz
will actually try to run, but it will be abort because of the following
assertion error:
"compiz: nv50_pc_emit.c:863: emit_flop: Assertion `STYPE(i, 0) == 0x09'
failed."

It seems that this only happens with PCI-E cards that have the NV50 chip.
