I feel like you're wasting my time. This is the fourth time in a row you've reported something I can't reproduce. At least this time the instructions work, but I've tried it a dozen times and it doesn't produce the error you're showing. $ git branch * (HEAD detached at 5404a7f1c21c) ... [ 0.000000] Linux version 4.20.0-rc1-00012-g5404a7f1c21c (willy@bobo) (gcc version 8.2.0 (Debian 8.2.0-9)) #4 Mon Dec 17 23:28:21 EST 2018 ... [ 9.848471] test_uuid: all 18 tests passed [ 11.019267] XArray: 19496249 of 19496249 tests passed Your logs show it failing every time. I can't help but wonder if it's something else in your setup that's causing it to fail -- maybe the machines doing the testing are overloaded?
