I've a similar bug occurring on the following kernel versions: * 5.0.0-23-generic * 5.0.0-25-generic * 5.0.0-27-generic
However, quite a few things are different in my case. As seen in logs, "Link is Down" is quickly followed up by "Link is Up" message, but interface fails to serve any packets. As far as packet statistics go, packets are transmitted, but never received. Kernel logs also show this interesting backtrace: 12:04:55 kernel: ------------[ cut here ]------------ 12:04:55 kernel: NETDEV WATCHDOG: enp3s0f1 (r8169): transmit queue 0 timed out 12:04:55 kernel: WARNING: CPU: 4 PID: 0 at /build/linux-hwe-zHO4ZF/linux-hwe-5.0.0/net/sched/sch_generic.c:461 dev_watchdog+0x221/0x230 12:04:55 kernel: Modules linked in: ccm ipt_MASQUERADE nf_conntrack_netlink nfnetlink xfrm_user xfrm_algo iptable_nat nf_nat_ipv4 xt_addrtype iptable_filter bpfilter xt_conntrack nf_nat nf_ 12:04:55 kernel: intel_rapl_perf rtsx_pci_ms asus_nb_wmi snd joydev input_leds mei_me asus_wmi soundcore memstick serio_raw sparse_keymap mei mxm_wmi processor_thermal_device intel_pch_the 12:04:55 kernel: CPU: 4 PID: 0 Comm: swapper/4 Tainted: P OE 5.0.0-23-generic #24~18.04.1-Ubuntu 12:04:55 kernel: Hardware name: ASUSTeK COMPUTER INC.

There is no relevant information in dmesg except for the "link down" message. The work around is to just keep rebooting the computer until it eventually works; sometimes this may take up to 7 reboots. The first set of attached log files were generated while the ethernet was working. The second set are generated on the 5.0 HWE kernel when the ethernet was NOT working. Note that this is a regression. Ubuntu 16.04 ran on this computer for three years without the ethernet doing this even once. Unloading and loading the r8169 module will eventually make it work.
