Just an update: So I re-ran with K Prateek's suggestion for a night
with no trouble, and then after I saw sched/core was updated I started
over with that as of 130fc7bdfadb ("sched/fair: Unify cfs_rq
throttling via account_cfs_rq_runtime()"), and its been running the
same stress testing for almost 40 hours without any apparent issues.

So yeah, I'm pretty sure the b6eee96843e8 ("sched/fair: Fix overflow
in vruntime_eligible()") fix resolved what I was hitting.

thanks!
