If you _don't_ have a crash dump I suggest finding what's getting in
the way of crash dumps so you can get them.  You can use, e.g.,

sysctl -w debug.crashme_enable=1
sysctl -w debug.crashme.panic=1

to trigger a panic in order to test crash dumps.

Typical causes:

1. no dump device configured in /etc/fstab
2. dump device is too small
3. NetBSD doesn't know how to dump to that kind of dump device
