--- Comment #14 from Chris Wilson <chris at chris-wilson.co.uk> ---
To actually reconstruct the original bug where the guc was executing contexts
out of order, you have to disable trickle feeding the guc. If you bump the
queue depth up to say 128, that should restore behaviour similar to the
original case.
