           Summary: OpenGL applications cause kernel to complain "Going to
                    lose  the write domain"
           Product: DRI
           Version: XOrg CVS
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM modules
        AssignedTo: dri...@li...
        ReportedBy: bg...@gm...


On Fedora rawhide the kernel dumps the following messages to the log at a
blinding rate while running an opengl application (I know it happens when I run
glxgears and it seems compiz as well, my only two test points),

Sep 16 14:14:50 mercury kernel: [drm:i915_gem_execbuffer] *ERROR* Going to lose 
the write domain on obj 38 size 16777216
Sep 16 14:14:50 mercury kernel: [drm:i915_gem_execbuffer] *ERROR* Going to lose 
the write domain on obj 40 size 16777216

Meanwhile, glxgears consistently shows 40fps without compiz. compiz produces 30
fps and down to 14 while switching workspaces with the desktop wall plugin.

There is a fedora bug for this open at
https://bugzilla.redhat.com/show_bug.cgi?id=462495.
