--- Begin Message ---Source: linux Version: 4.19.28-2~bpo9+1 Severity: important X-Debbugs-Cc: debian-ad...@lists.debian.org User: debian-ad...@lists.debian.org Usertags: needed-by-DSA-Team Hi, after upgrading conova-node01.debian.org to the stretch-backports kernel to see if #929359 was reproducible, it started dropping packets. This was not happening prior to the upgrade. Running "ip link set dev eth0 mtu 1504" seems to make things work.
