How to properly report drm-kmod bug
reddit / freebsd

I have an AMD 6900XT in my system. However, when using the drm-kmod
driver, my system hard-locks/resets very consistently..

I'm running Wayland, but if the bug occurs when a Wayland session is
active, the system hard locks and reboots.. I recently tried a stress
test without launching X or Wayland, and got the error shown in the
attached image. This results in a locked up system, with a hard reboot
the only option.

Oddly, this happens much more frequently if the CPU is at a heavy
load.. I even upgraded power supplies hoping that was the issue, but
I'm still getting hard locks after the upgrade.

My question is, as someone relatively new to the FreeBSD community,
what's the "proper" way to report this bug? What files should I
attach?

Thanks a bunch. I've ordered an older AMD GPU to (hopefully) avoid
this for now, but I'd definitely like to find a real fix..

Better to start with a simple analysis before punting to devs. You'll
need to gather the same information either way.

Great! Exactly what I was looking for. Thanks, I'll figure this out
this weekend.
