>Description:
I have now had two kernel panics with the above message. In the first case, I found the machine had rebooted itself overnight and in the second I was editing a file when it froze and rebooted itself. I found the following messages in /var/log/messages:

The machine I am running NetBSD on is a Raspberry Pi 3. There is nothing connected to it other than a keyboard, mouse and wireless dongle i.e. I am not running anything special on it.

Is there anything I can do to get more information on this panic if it happens again?
