Yep, I'm narrowing it down. Happens sometime between these two commits: commit 23626bcf3bd987f7a5e03b93bec8450b10421c31 Author: Lorenzo Bianconi <[email protected]> Date: Mon Jul 2 17:19:22 2018 +0200 OVN: add ICMPv6 time exceeded support to OVN logical router commit 6690de401904217e9c824197b0aa84d68d2c363a Author: Greg Rose <[email protected]> Date: Thu Jun 28 20:31:26 2018 -0700 datapath: Add missing code in ip_tunnel_lookup() Thanks, - Greg
