device not responding post upgrade with ipv6 disabled

[mpadilla2]

If you are experiencing a problem with your device not responding after the most recent upgrade AND you disable ipv6 with say uEnv.txt you are likely experiencing the following bug:
https://bugs.freedesktop.org/show_bug.cgi?id=90103#c2

A downgrade to systemd 218-2 is a workaround that I have tested and can confirm works. I have set pacman.conf to:

$this->bbcode_second_pass_code('', 'IgnorePkg = systemd')

Until the bug is fixed.

Another workaround is to go ahead and use systemd 219 AND disable ipv6 with sysctl instead of with optargs in uEnv.txt.

First remove /boot/uEnv.txt OR the entry that disables ipv6. Then in /etc/sysctl.d/ create 40-ipv6.conf and add the following:

$this->bbcode_second_pass_code('', '# Disable IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
net.ipv6.conf.tun0.disable_ipv6 = 1')

In my example I am disabling for devices eth0 and tun0 as I have an ethernet device and am using a vpn with tun0. I hope this helps someone else. I've tested this configuration and it works with systemd 219 on pogo E02.

Thank you friend. But did not work. Now i can't even ping. Device do not enter on the network.
I supose it should be done on another computer, since i have no interface at all to edit any config, ok?
I didn't have a /boot/uEnv.txt, so i justr created the /etc/sysctl.d/40-ipv6.conf file with the content.
Any help?

PS. After some time, started to respond ping, but that's all. Nothing more.

Never mind. Already working. A missing drive at fstab was the problem.

Thank you for your help.
