--- Comment #1 from Kubilay Kocak <koobs@FreeBSD.org> ---
Thank you for the report Stefan. Could you please include, as attachments:

- pkg version -v output
- pciconf -lv output
- /var/run/dmesg.boot output
- screenshot of the panic message (if available)

It would be great, if you can, to enable automatic crash dumps and processing,
and to provide a panic backtrace. It may also be useful to build nvidia and drm
ports WITH_DEBUG before doing so.
