--- Comment #4 from Ian Romanick <idr at freedesktop.org> ---
I was not able to reproduce this failure during a full CTS run on a Skylake
GT3e NUC.  This problem is likely timing related or possibly related to some
software outside Mesa (kernel, X, Wayland, something?).

My system is:

kernel-4.14.6-300.fc27.x86_64
libwayland-server-1.14.0-2.fc27.x86_64
gnome-session-wayland-session-3.26.1-1.fc27.x86_64
libdrm 2.4.89 (commit 831036a6)

Looking at the output from the failure (and since it fails sporadically on the
CI), I'm definitely leaning towards timing.  Is
glMemoryBarrier(GL_BUFFER_UPDATE_BARRIER_BIT) maybe not doing the right thing?
