I did a re-run today and surprisingly it passed: main.order_by_innodb 'innodb' w2 [ pass ] 84
https://buildd.debian.org/status/fetch.php?pkg=mariadb-10.6&arch=s390x&ver=1%3A10.6.11-1&stamp=1670206361&raw=0 Maybe the issue is sporadic? But also the first day I saw this I re-ran the build and it did not pass, so could also be the test behaviour was dependant on some dependency that updated in the past week?
