safecore, and analyze that (ddb.onpanic=0)
Should default on:
|marie is 105% grep savecore /etc/defaults/rc.conf
|savecore=YES savecore_flags="-z"
| savecore_dir="/var/crash"
assuming enough space in /var/crash (taking into account the number in
/var/crash/minfree) and enough space on the designated dump partition.
You'll need the netbsd.gdb from the same build as your then running kernel
to see the symbols; the kernel saved alongside is, normally, the running
one (from the time of the savecore) thus too symbol-lacking to be very
useful.
