            Bug ID: 291239
           Summary: Kernel panic when running most wayland WMs (nvidia)
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs@FreeBSD.org
          Reporter: solidwarea@outlook.com

I apologize in advance if I've categorized this incorrectly or if the reason
for my issue is due to the lack of proper research, but I've tried my best but
I can't figure out what's wrong.

I am able to start Wayfire and Sway/SwayFX properly, but running KDE on Wayland
using the tty and sddm leads to a kernel panic, and so does running niri.
Running hyprland gives me a blank screen for a few seconds then my system
restarts. Both niri and KDE have on one or two occasions loaded the desktop for
a few seconds, but freezes immediately after that, then goes on to crash and
restart my system again.

Specifications:

Nvidia GTX 1660 Super
Driver version: 580.105.08 (graphics/nvidia-drm-kmod)
FreeBSD 15.0-RC3 (I believe I got the same result on 14.3-Release when I tried
it)

The numbers may be a bit off since I had to extract the output from a photo of
my screen as I otherwise couldn't figure out how to save it to my computer. If
that is of any importance, let me know so that I can double check to make sure
everything is in order.

Thank you!
