Not really sure how to properly debug this, let me know if there is anything I can do to help

Looks like this issue is similar to #30. What this means is that the proprietary WiFi drivers for the UDM are currently incompatible with the edge3 kernel (due to ABI differences).

You could try to build a custom kernel yourself and diverge as little as possible from the stock kernel (to prevent ABI changes) and hope that the WiFi driver works.

Alternatively, you could blacklist the WiFi driver, but that obviously means that WiFi does not work anymore. In #30, I mentioned a possibility of using the open-source mt76 driver. However, I expect getting that working is a rather complex task.

Thanks for the explanation! It was more curiosity in general anyway. I might give it a try when I have some time to kill :smile:
