Public bug reported: I have noticed that the network stopped working on my desktop after I've suspended the system and woke it up. On dmesg there are messages like:
[ 150.877998] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready [ 150.944101] do_IRQ: 3.37 No irq handler for vector [ 150.944105] r8169 0000:01:00.0 enp1s0: link down [ 150.944180] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready When using Xenial (from a different install), this problem is not happening. This is happening on Bionic. There are only two ways to restore connectivity: 1) Reboot the system; 2) Remove the r8169 module and reinsert it with modprobe. The motherboard is a AsRock H55M-LE and the Ethernet controller is: 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
