For what its worth, bisect points to the following commit:
147f3efaa241 ("sched/fair: Implement an EEVDF-like scheduling policy")
Which was merged into bpf-next 3 days ago as a part of:
3ca9a836ff53 ("Merge tag 'sched-core-2023-08-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip")
Scheduling changes uncovered some old race condition?
