Hello All! My home laptop running FreeBSD did panic yesterday. It is running: root@mordax:~ # freebsd-version 12.3-RELEASE-p5 root@mordax:~ # uname -a FreeBSD mordax 12.3-RELEASE-p5 FreeBSD 12.3-RELEASE-p5 GENERIC amd64 I tried kgdb and got: root@mordax:~ # kgdb /boot/kernel/kernel /var/crash/vmcore.0 GNU gdb (GDB) 11.2 [GDB v11.2 for FreeBSD] Copyright (C) 2022 Free Software Foundation, Inc.

Any hints or tricks? Many thanks to All, Luciano. -- /"\ /Via A.
