Looks like pmap_invalidate_range using smp_targeted_tlb_shootdown using _mtx_lock_spin_cookie. I'll note that I had no trouble with -r349444 building world or kernel repeatedly, including when I originally build -r349794 to upgrade. The below is from my 2nd buildworld buildkernel under -r349794 (but the 2 builds were not from scratch ones). # more /var/crash/core.txt.2 FBSDFSSD dumped core - see /var/crash/vmcore.2 Sun Jul 7 02:26:36 PDT 2019 FreeBSD FBSDFSSD 13.0-CURRENT FreeBSD 13.0-CURRENT #24 r349794M: Sun Jul 7 01:55:57 PDT 2019 markmi_at_FBSDFSSD:/usr/obj/amd64_clang/amd64.amd64/usr/src/amd64.amd64/sys/GENERIC-NODBG amd64 panic: spin lock held too long GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
