Out of curiosity, how does one view the coredump file and get stack
traces from it?


These are reasonable places to start:

http://wiki.dragonflybsd.org/index.php/Kernel_Debugging_in_DragonFly_BSD
One little thing that might not be obvious to a newcomer:  any time you
build a new kernel, the 'old' kernel is stripped of debugging symbols
and saved as kernel.old.
If you need to reboot kernel.old (e.g. the new kernel panics on boot)
then be careful to point gdb to the 'new' kernel which still has the
debugging symbols.
yea.  savecore might even not work if called from the .old kernel.  then 
you will have to point savecore manually to the panic'ed kernel.

cheers
