Nice. Does suspend/resume work? I've heard that it does on Ryzen Mobile, but more confirmations would be good.

ZFS boot environments. Forget anything you've ever heard about actual (GPT) partitions :)

I also can see the amdgpu/picasso firmware being loaded with 12.1-RELEASE and the drivers / firmware compiled and installed from FreeBSDDesktop, and I’m just now rebuilding xorg from ports to see how that goes.

Yeah, I use current with a non-invariants kernel (e.g. generic-nodebug) everywhere.
