Using drm, mesa, xorg from current git glxinfo throws the following error:

Minor opcode of failed request: 7 (DRI2GetBuffersWithFormat )
Resource id in failed request: 0x5600002

Can't reproduce it here. Can you bisect?
I pulled again, and this issue seems to be gone, maybe some hickup in the chain... Sorry for the noise...
