dtech That looks like a kernel crash to me.
Has anything changed in your environment since December when it was working?
- Updated LibreELEC?
- Different raspberry pi? (3 vs 4)
I'm not sure what to suggest other than perhaps trying to update SteamLink in the application. (There should be an option in the settings dialog). It should fetch the latest SteamLink + dependencies.
Hopefully this resolves the issues, as I can't reproduce it here (Typical developer response. "It works on my machine")
