Hello,
I had a kernel panic while reproducing a video with mpv.
It's my first kernel panic with OpenBSD, so I didn't know how to use
ddb(4). Since I'm running my http and smtp server in this machine I
cannot entertain myself too much reproducing the panic to get more info.
That's why I don't include the per cpu trace and other additonal info as
explained in ddb.html, sorry! But, if you need it let me knonw and I'll
try my best.
