The failure is that the number of reports do not fall in this range. Machines affected: skl and bdw Repro rate: 0.6% The test seems to ignore spurious reports and hence falls short of 45% by 10 - 15 reports. Test logic must be updated to reflect spurious reports by checking if the timestamp delta between the previous and current reports is greater than the periodic interval.
