Description Roger Fujii 2024-01-12 09:51:42 UTC 
Just updated to 14.0-RELEASE yesterday.   Took a nap and came back and the system was at a login screen.   It was updated from 13.2-RELEASE-p8.

Here is the stack dump - some added info - ipv6 is not configured (or at least, it's just at default), and it runs a webserver that has 80/443 port forwarded from the internet from a router:

This looks like a dup of PR 273890?  Gleb, should we perhaps release an EN for 14.0 for this?  I can help get that done if so.
Comment 2 Gleb Smirnoff freebsd_committer freebsd_triage 2024-01-13 07:53:39 UTC 
Yes, this is already fixed in 14.0-STABLE.

Mark, if you have time for issuing EN, please. Looks like it worth to
make one.
