That's a different failure case, not the bug reported here. That is actually the expected failure on the current kernel.
Comment 11 Chris Wilson 2016-01-28 10:14:14 UTC 
As the most recent entry here is for a dupe of the big-copy-xy fail, and the original bug is fixed (bug 91116 and friends), marking as resolved.
