No problem. I will contact Mark. 

Primarily looks like platform / kernel version issue. intel_get_boolean() for 
I915_PARAM_HAS_EXEC_FENCE is false, but I see following in
i915_drv.c:915_getparam in kernel, no clue why that would come false
in UMD.

...
        case I915_PARAM_HAS_EXEC_FENCE:
                /* For the time being all of these are always true;
                 * if some supported hardware does not have one of these
                 * features this value needs to be provided from
                 * INTEL_INFO(), a feature macro, or similar.
                 */
                value = 1;
                break;
