The CI Bug Log issue associated to this bug has been updated. ### New filters associated * ICL: igt@gem_exec_schedule@preemptive-hang-vebox - incomplete - missed_breadcrumb vecs0 missed breadcrumb at intel_breadcrumbs_hangcheck - https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_194/fi-icl-u3/igt@gem_exec_schedule@preemptive-hang-vebox.html
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.
Also, not seen again in 700 runs. Resolving.
