Details

Description:

A machine that has a virtio network interface to a layer two network does not respond to ARP requests
for its IP on that interface anymore after the kernel was upgraded by installing the linux-lts-4.1.9-2 package.
A downgrade to 3.14.50-1-lts makes it work again. That was the only change. A simple reboot did not help.
The kernel is the definitive cause. There are no ebtables rules.

Additional info:
* package version(s):
linux-lts-4.1.9-2

* config and/or log files etc.


Steps to reproduce:

Install linux-lts-4.1.9-2 on a machine
make some virtio interface to a network
assign IPs
Watch the box not sending arp replies.
This task depends upon

Maybe some module got lost. Please diff the kernel config checking for your missing module. lsmod with the old kernel booted may help. Check also dmesg/journalctl systemlog.
