I might be wrong but  I think you are talking about 
igt@syncobj_timeline@transfer-timeline-point testcase which seems to be

green in CI now 
https://intel-gfx-ci.01.org/tree/drm-tip/igt@syncobj_timeline@xxxxxxxxxxxxxxxxxxxxxxxxxxxx

Lucas found out that the issues got fixed after ec8d985ff26f ("drm: use 
dma_fence_unwrap_merge() in drm_syncobj")
