Hi, While I was trying out intel-git as well as mesa-i915git on my i945GM based laptop I saw a few of the following messages in syslog: [ 3045.237121] [drm:i915_gem_do_execbuffer] *ERROR* Invalid object handle 83886080 at index 0 Any idea where they could come from, and what I can do to investigate it further? Thanks, Clemens
