This is intermittent but happens frequently on two lumpy DUTs (see below) this week. I only observed the failures on these 2 lumpy devices but not other boards. It looks like that these 2 lumpy devices may need to be replaced.

On the other hand, do we need lumpy? They are pretty old (sandybridge) and we have peppy (haswell) for Intel "big" cores.
