--- Comment #7 from Adam Jimerson <vendion at gmail.com> ---
Leaving this closed for now as for some reason the crash dumps either did not
get exported/saved so don't know how useful this is but I did see that this
happened again yesterday and all I have to go off of is the stacktrace from
/var/log/messages:

I can upload the current kernel I'm using (FreeBSD 12.1-p6 GENERIC) if need be,
but if it happens again and I get crash dumps for it I'll reopen.
