It runs several stress-ng tests against the target. In my
reproduction, I've disabled all but one, and that is 'chdir'. Here's
the invocation:

stress-ng --aggressive --verify --timeout 240 --aio 0 --hdd-opts dsync
--readahead-bytes 16M -k

This is the only stress-ng command that runs after boot/fresh-mkfs.
However, as I mentioned, this stress-ng command alone did not appear
to trigger the issue. I suspect that this is due to sysctls that cert
sets before the running the test, but I have not attempted to prove
that yet.
