I wrote a quick and dirty script to extract the data from my logs to see
if the regression might be older then I remembered. I filtered out the
obviously wrong configured runs (e.g !RT). It looks like the first
recorded outlier is around 5.9.0-rt16. Does this already help or do you
want me to bissect it down?
