Comment 67 for bug 1815101

It is reproducible on a VM with a simple netplan file with only one ethernet and one bond interface:

network:
    ethernets:
        n1p1:
            match:
                name: ens192
    bonds:
        bond_all:
            interfaces:
            - n1p1
            parameters:
                mode: balance-rr
            addresses:
            - 10.1.1.206/24
            nameservers:
                addresses:
                - 10.1.1.1
            routes:
            - metric: 150
                to: 0.0.0.0/0
                via: 10.1.1.1

This always produces following logs, together with a brief network loss:
