If you need to provide crash data to the pfSense developers, please follow this document.
First, you need to install the developer kernel. To do so, first run "rm /boot/kernel/pfsense_kernel.txt" from a command prompt. Then upgrade your pfSense release to the same release it is currently running, but when upgrading, you will have a kernel selection box. Select the Developer kernel option.
//You most likely want to enable a serial port unless you wish to hand scribe about 10+ pages of text...//
__**Crash it!**__
Type each of these commands at the db> prompt:
%%
bt
bt all
show allpcpu
show alllocks
show lock
ps
set $lines 0
allt
show lockedvnods
reset
%%
If you wish to build your own developers kernel with debugging:
You need the following in your kernel file (or use [[http://cvs.pfsense.com/cgi-bin/cvsweb.cgi/tools/builder_scripts/conf/pfSense.6.DEBUG?rev=1.3 this]] kernel configuration file):
%%
makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols
options KDB # Enable kernel debugger support.
options DDB # Support DDB.
options GDB # Support remote GDB.
options INVARIANTS # Enable calls of extra sanity checking
options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS
%%
