Comment 2 Chris Wilson 2019-01-25 13:21:53 UTC
Missed breadcrumb is perfectly normal debug here, it's the precursor to us stopping a GPU hang. The machine disappeared between the breadcrumb timer and the hangcheck timer.
Comment 3 Francesco Balestrieri 2019-02-11 08:50:27 UTC
Also, not seen again in 700 runs. Resolving.
