Adding '-smp 16' and CONFIG_KCSAN_REPORT_ONCE_IN_MS=100 as you
suggested below, I was able to get it running under kunit.py with the
following results:
Testing complete. Passed: 168, Failed: 0, Crashed: 0, Skipped: 1, Errors: 0
Elapsed time: 92.642s total, 0.003s configuring, 4.592s building,
88.009s running

Nice!
