This is a mock reproducer of this issue by faking a 20s delay in virtio- net after its link is up.
To enable that, user needs to build virtio-net with the hereby attached patch, and insert: "echo 1 > /sys/module/virtio_net/parameters/droppkt" in the /usr/sbin/kdump-config before the network dump procedure. It'll introduce a 20s delay in packet transmission, causing the issue reported in this LP to be reproduced. This patch was developed in Bionioc 4.15.x kernel. ** Patch added: "0001-NOT-UPSTREAM-virtio-net-Add-droppkt-param-to-force-d.patch" https://bugs.launchpad.net/ubuntu-power-systems/+bug/1681909/+attachment/5275113/+files/0001-NOT-UPSTREAM-virtio-net-Add-droppkt-param-to-force-d.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1681909 Title: kdump is not captured in remote host when kdump over ssh is configured To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1681909/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
