Build machine (mini-tower) performed the update (r362008 -> r362045)
without issue, but my laptop panicked quite early on -- before the dump
device was configured.

I have taken and placed a couple of screen shots in
http://www.catwhisker.org/~david/FreeBSD/head/r362045/

Looking at the displayed backtrace, I see:

--- trap 0xc ...
futex_xchgl_reslover()
elf_reloc_internal()
link_elf_reloc_local()
link_elf_link_preload_finish()
linker_preload()
mi_startup()

Any clues?  I'm hapy to poke at it or try patches.

Booting from kernel.old (r362008) still works:
FreeBSD g1-55.catwhisker.org 13.0-CURRENT FreeBSD 13.0-CURRENT #46 r362008M/362008: Wed Jun 10 04:19:33 PDT 2020     root_at_g1-55.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY  amd64 1300097 1300097

Thanks!

Peace,
david

Someone who suggests he can "pardon himself" calls for "LAW & ORDER" -- right.
