Some experiments, 1. Try the driver mentioned in #9. The bug still exists.
2. Blacklisted alx and inserting the module after the booting, the system is still failed to connect to wired network.
3. echo 1 > /sys/class/net/eth0/device/reset , the system can connect to wired network.
Since both re-enable network and re-insert module involved NIC reset (power down then power up), I suspect this it may be a hardware bug.
