--- Comment #3 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Last Valley GPU hang I've seen on BDW GT2 was with 
f24cf82d6db290a88abfff0669d2c5e2aa463901 2017-08-19

Somewhat later, there have been GPU hangs with GfxBench T-Rex onscreen &
offscreen with
4d807d7fe272db97fb9e20800872d5970fa2696d 2017-08-22
f0602dc92044ea6d738d0e539e52f938a41f6093 2017-08-23

On BDW GT3 last Valley GPU hang was bit later with 
5d2205fafb5d244af658de5e3c38c6cc805ae345 2017-08-24

However, on same commit and later there have been also GfxBench T-Rex onscreen
& offscreen GPU hangs with:
