Spotted a problem that may be affecting snb & hsw,

commit 90babd3f12707dfabaa58bb18f6b8e22636b6895 (upstream/master)
Author: Chris Wilson <chris@chris-wilson.co.uk>

    lib: Fix gem_measure_ring_inflight
    Any use of __for_each_physical_engine breaks library use of
    for_each_physical_ring and in this case (e.g. gem_busy/close-race) leads
    to GPU hangs.

This and the reset-stress on snb/hsw might be affected.

This should be one problem solved at least, so lets claim it was this one!
