What can I do to fix this?
Which release are you using (see “head -n 1 /etc/nv_tegra_release”)? Also, are you able to ping, and can you do ssh login? If so, try to use dmesg to see what it says before the problem occurs, and then again after…“before” is just so you know what is old, “after” to see what changed. If ssh fails, then that is another clue and you’ll likely need serial console.
