My apologies. I was using "cyclictest" from git repository: node-0> git remote -vv origin git://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git (fetch) origin git://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git (push) And I was on stable/1.0 branch!! (I had thought pointing to repo in kernel.org I would be current, but I should have checked.) I compiled version 2.3 (tip of "main" branch) and it works as expected.
