Note, SNB doesn't support pstore so it could be NMI/kernel OOPS. However, if it was OWATCH it would be noticed in run.log.

Comment 1 Chris Wilson 2017-11-24 10:45:37 UTC

live_hangcheck should be capable of causing a machine hang in snb (because snb).

Comment 2 Marta Löfstedt 2017-12-01 12:37:04 UTC

I will use this bug to pile up SNB incompletes timeout/system hang as for other machines.

This is a Meta bug to capture all unexplained incompletes on SNB
