This looks to be my solution. I usually can trigger the issue with 2 or
3 runs of tracing hackbench. I just finished running it 10 times and it
hasn't triggered. I'll let it run a few more times but I'm going to
disable PREEMPT_DYNAMIC in my tests, and hopefully it doesn't fail due
to this anymore.
