I'm not sure if it's this one, or 3623630, the following i386 tests
all panicked:

https://ci.freebsd.org/job/FreeBSD-head-i386-test/9681/console

00:11:31.669 lib/libc/net/protoent_test:protoent  ->  panic:
__rw_wlock_hard: recursing but non-recursive rw vm object @
/usr/src/sys/vm/vm_object.c:869

https://ci.freebsd.org/job/FreeBSD-head-i386-test/9682/console
(includes the fix or r362363)

00:27:53.864 bin/pkill/pkill-j_test:main  ->  Sleeping thread (tid
100115, pid 65628) owns a non-sleepable lock

https://ci.freebsd.org/job/FreeBSD-head-i386-test/9683/console

00:02:26.917 bin/pkill/pkill-j_test:main  ->  Sleeping thread (tid
100152, pid 26582) owns a non-sleepable lock

Can you help check these?

Thanks,
