Comment 75 for bug 1861936

I'm having the exact same issue on my RPi 3. I've been using the Pi for a very long time now and never had an issue. But since last week I updated the OS to the latest Raspberry OS and the Pi is now running as a K3s master node. Since then the Pi keeps crashing like this. I've having a lot of network traffic, way more than it had before it was used as a k3s master node.

About 2 days ago I tried the rpi-update which Christopher provided, and since then the Pi is running without any crashes (yet). Almost 48 hours already, where before it wasn't able to run 24 hours straight.
