The easiest way is to have a serial console. that is VERY easy to do. simply add the line console="comconsole" to the file /boot/loader.conf After that you can also work on getting core-dumps (man dumpon) and use gdb to get backtraces etc. Some machines don't clear all of ram so "dmesg" can sometimesm show panic messages from the last session too.
