Hi all,
Seeing significant issues with IPv6. After some time, IPv6 completely seems to stop working. IPv4 is unaffected.
Re-connecting to wifi seems to restore IPv6 connectivity.
However, various things (ssh, firefox) stop working completely. Open ssh sessions "freeze". Web page requests time out.
At the same time, I can access IPv6 resources from other machines which do not run NetworkManager.
Next time this occurs, I hope to have some time to diagnose this problem further. In the meantime, is anyone else seeing such breaking wrt IPv6?
