           Summary: on Intel 945G, (beryl or compiz) + glxgears =
                    DRM_I830_CMDBUFFER: -22
           Product: Mesa
           Version: 6.5
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: Drivers/DRI/i915

        ReportedBy: [EMAIL PROTECTED]


Hello,

with beryl or compiz activated, moving, with mouse, glxgears' window to 
next desktop crash glxgears with error DRM_I830_CMDBUFFER: -22.
I get this error too with blender when I rotate the desktop cube.
Another way to get this error is launching "wine blender_for_windows".

"dmesg | tail -2" give this :
[ 9031.808089] [drm:i915_emit_box] *ERROR* Bad box 65407,301..171,601
[ 9031.808099] [drm:i915_cmdbuffer] *ERROR* i915_dispatch_cmdbuffer failed

I've seen a (maybe) similar bug for 965G chipset, fixed in mesa 6.5.2 
(http://lists.freedesktop.org/archives/xorg/2006-November/019943.html ; 
http://lists.freedesktop.org/archives/xorg/2007-January/020826.html ;  
http://bugs.debian.org/394311).

I have an intel 945G chipset and I am on Ubuntu Feisty, with mesa
6.5.2-3ubuntu7, xserver-xorg-video-intel 2.0.0-1feisty1 and xserver-xorg-core
1.3.0.0.dfsg-1feisty1 (Ross Burton packages).
