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? rpi3 signaltest 5.4.59-rt36 382 0_signaltest t0-max-latency : fail 220.00 382 0_signaltest t0-avg-latency : pass 47.00 382 0_signaltest t0-min-latency : pass 20.00 rpi3 signaltest 5.6.19-rt12 368 0_signaltest t0-max-latency : fail 221.00 368 0_signaltest t0-avg-latency : pass 45.00 368 0_signaltest t0-min-latency : pass 21.00 rpi3 signaltest 5.9.0-rc8-rt12 813 0_signaltest t0-max-latency : fail 214.00 813 0_signaltest t0-avg-latency : pass 45.00 813 0_signaltest t0-min-latency : pass 20.00 rpi3 signaltest 5.9.0-rc8-rt12 874 0_signaltest t0-max-latency : fail 217.00 874 0_signaltest t0-avg-latency : pass 45.00 874 0_signaltest t0-min-latency : pass 20.00 rpi3 signaltest 5.9.0-rt16 963 0_signaltest t0-max-latency : fail 321.00 963 0_signaltest t0-avg-latency : pass 47.00 963 0_signaltest t0-min-latency : pass 21.00 rpi3 signaltest 5.9.1-rt19 1038 0_signaltest t0-max-latency : fail 341.00 1038 0_signaltest t0-avg-latency : pass 46.00 1038 0_signaltest t0-min-latency : pass 20.00 rpi3 signaltest 5.9.1-rt20 1079 0_signaltest t0-max-latency : fail 318.00 1079 0_signaltest t0-avg-latency : pass 47.00 1079 0_signaltest t0-min-latency : pass 21.00 rpi3 signaltest 5.10.0-rc1-rt1 1118 0_signaltest t0-max-latency : fail 415.00 1118 0_signaltest t0-avg-latency : pass 53.00 1118 0_signaltest t0-min-latency : pass 23.00 rpi3 signaltest 5.10.0-rc2-rt4 1163 0_signaltest t0-max-latency : fail 340.00 1163 0_signaltest t0-avg-latency : pass 53.00 1163 0_signaltest t0-min-latency : pass 24.00
