Probably because I deleted that i2c acpi attachment at some point, because it didn't seem to actually work. 

>Aside - since the builtin netifs are basically useless for us, any suggestions on USB wifi dongles? I tried a few from my parts piles, but all of them were unstable Realtek trash. I know Atheros chips are usually a good bet in Linux land - does that hold true in FreeBSD as well?

Not sure how common Atheros is on USB.. Ralink is fine I think? Actually Realtek wifi shouldn't be unusable too..

For USB Ethernet though, I recommend the "Nintendo Switch compatible" ASIX chips (axge).


By the way, did you get any different firmware builds in the meantime? That don't have everything suspiciously routed to the SMMU in IORT..
