--- Comment #2 from Kubilay Kocak <[email protected]> ---
@Reporter Thank you for your report. Could you please include additional
information:

- exact uname -a output
- /etc/sysctl.conf contents (as an attachment)
- pkg info drm-fbsd13-kmod (output as an attachment)
- Include screenshot mentioned in comment 1 as an attachment

If you're able to configure a debug kernel and kernel core dumps [1] to obtain
a detailed backtrace, that would be great
