Can you post your ipi_stress test? I'm curious to see if I can repro, and also
very curious as to what might be unique about your test. I haven't been able to
repro the syzbot test, nor have I been able to repro by killing VMs/tests.
Did you test with CONFIG_PREEMPT=y?
(BTW, the fact that it reproduces under 5.17 is a mixed blessing,
because it means that we can analyze/stare at a simpler codebase).
