Hi, after upgrading to 7.6, kernel 3.10.0-957.1.3.el7.x86_64, at boot instead of the GUI login screen I got two lines like this:
IPv6: ADDRCONF(NETDEV_UP): em1: link is not ready IPv6: ADDRCONF(NETDEV_UP): em1: link is not ready
The server is accessible via ssh on IPv4

IPv6 is configured as IGNORE in NetworkManager.
I tried the following with the same result:
net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.all.disable_ipv6 = 1
and reboot, no effect
Setting an automatic IPv6 address: no effect.
Suggestions?

The output you see is probably unrelated to the problem. Check the output of "systemctl status gdm" and /var/log/Xorg.0.log

Thank you! Your suggestion has been very helpful.
systemctl status gdm showed GDM running as expected, but /var/log/Xorg.0.log had many error lines like this:
(EE) FBDEV(0): FBIOPUTCMAP: Invalid argument
The solution proposed in https://www.centos.org/forums/viewtopic.php?t=55418 was not applicable because fbdev is correctly installed.
Widening the search I found this: https://lists.debian.org/debian-x/2014/07/msg00010.html
The solution was to create a file /etc/X11/xorg.conf.d/99-fbdev-fix.conf with this content:
Section "Device" Identifier "Card0" Driver "fbdev" EndSection
And restart.
