BTW, if you run procstat -k 11 a few times during the condition, does TID 100006
typically have or not have "lock_mtx softclock" substring in its stack?
Not. I ran 'procstat -k 11 | grep 100006' about 20 times, and all but
one looked like this:
11 100006 intr swi4: clock mi_switch ithread_loop
fork_exit fork_trampoline
The one that didn't looked like this:
11 100006 intr swi4: clock mi_switch turnstile_wait
_mtx_lock_sleep _mtx_lock_flags lock_mtx softclock
intr_event_execute_handlers ithread_loop fork_exit fork_trampoline
It just ran away again with the only change being cx_lowest=C1. I'll try
changing the event timer next.
