NetBSD 11.0 amdgpu Ryzen Pro 2400G and WX3200

[P Gman <patrickgunsolley%gmail.com@localhost>]

Hello!

I've been using NetBSD 11.0 with a Ryzen Pro 2400G APU and llvmpipe.

I'm able to enable amdgpu in my boot.cfg:
menu=Boot with amdgpu:rndseed /var/db/entropy-file;load
drmkms_sched;load amdgpu;boot

After enabling, 50% of my boot attempts are met with a kernel panic.

Is there a known fix for this?

In the event that I am able to boot and log in, the system will freeze
after running startx.

AFAIK I'm using the system defaults for X, except with the following xinitrc:

~/.xinitrc
----------------------------------------------
if [ -f ~/.Xresources ]; then
  xrdb -merge ~/.Xresources
fi

exec i3
----------------------------------------------

I mentioned my Radeon Pro WX3200 because it produces the same results,
however it (supposedly) is supported by NetBSD's DRM stack (polaris
family).
