With the test "stress_inorder_work" disabled, both systems completed 100 iterations of tools/testing/selftests/locking/ww_mutex.sh successfully with the self-test as a module. With the self-test as a built-in, the systems survived: for N in {1..100}; do echo 1 > /sys/kernel/test_ww_mutex/run_tests done The main differences between the v2 contribution and this v3, is that the last patch is removed.
