Public bug reported:
When using ethernet (Realtek RTL8111/8168/8411 using built-in r8169
driver v2.3LK-NAPI), dhclient stuck at DHCPDISCOVER. When using static
IP, nm shows it's connected, but I can't ping anywhere.
This issue only shows up in 4.15.0-29.31. I tried the following versions
without issue:
1) 4.18.0-041800rc7
2) 4.16.0-041600
3) 4.15.0-23
4) 4.15.0-20
No issue on wifi (Intel 7260 iwlwifi) and USB ethernet (Dell D3100
Dock).
