Created attachment 574932 [details] Kernel .config file I am running a PC on sys-kernel/gentoo-sources-5.0.10. I need at least a 4.20.x kernel to support the quite new Intel Core i5-9600K CPU build in graphics. But 4.20 is end of development. The system runs IPv4 and IPv6 in a dual stack configuration. Since i have changed to 5.0.x SSH IPv6 sessions terminating at this PC hang after a few minutes. When I boot a 4.20 kernel everything is fine, when i reboot to 5.0.x SSH (and rsync) via IPv6 hang after a while. I have no idea how to track this down. There are no findings in syslog or dmesg. A change from openssl 0.9.8 to 1.1.0 did not show any difference.

Is this still an issue?
(In reply to Mike Pagano from comment #4) > Is this still an issue? No, it's no longer an issue. The problem vanished with 5.2 and I believe it was related to IPv6 privacy settings and expiration of the source address during active ssh sessions. I have now changed my setup from IPv6 stable-privacy (default with NetworkManager) to EUI64 combined with IPv6 privacy and a long valid lifetime. I appologize that i have forgotten to follow up this bugzilla.

No worries. Thanks for responding.
