For me the adjtime_failure call caused a kernel panic.

panic: Bad tailq NEXT(0xfffff80055d3d388->tqh_last) != NULL

@asomers It was passing for me.

Just to be sure, I set flag: all in /etc/security/audit_control but even then it passed without any issue

Passing in 12.0-CURRENT or 11.1? What is uname -a?

Nevermind. I forgot that I had locally reverted r334296.
