TrueNAS CORE crashes/reboots when testing hardware encoding/VAAPI

TrueNAS-13.3-RELEASE
Jail is running 13.3-RELEASE-p7
CPU is an AMD Ryzen 5 3400G (integrated Radeon RX Vega 11 GPU)

Here’s basically what I’ve done so far:

-added amdgpu to kld_list on host
-created devfs ruleset to expose /dev/dri and /dev/drm into the jail
-installed Mesa Gallium VAAPI drivers (FreshPorts -- graphics/mesa-gallium-va: Mesa Gallium VAAPI drivers)
-run vainfo --display drm

Result: I get the following output - then TrueNAS core becomes unresponsive/does a full reboot:

If they do, bad things may happen!

Debugging crummy DRM on 13.3 is probably going to be very painful, especially for an AMD GPU. Suggest you look at upgrading to SCALE at some point. Expect it will work there since the Linux drivers tend to be better maintained.
