AX88179 Gigabit Ethernet Reproducible: Happens maybe once a day or few days. Don't know how and why. Symptoms: Firefox stops being able to make any network connections. I need to kill it, because it's stuck even when closing. Everything else seems to be working fine (including stuff like https://github.com/debauchee/barrier).
