The "ethernets" autopkgtest for netplan.io 0.107-5ubuntu2 on s390x often fails with

AssertionError: systemd units changed without reload

Looking at the history of autopkgtest runs, it looks like that the error does not always occur during execution of a specific test. I've seen occurrences of this error during the following test-cases:

test_dhcp6 (__main__.TestNetworkd.test_dhcp6) ... FAIL
test_link_local_ipv4 (__main__.TestNetworkd.test_link_local_ipv4) ... FAIL
test_eth_mtu (__main__.TestNetworkd.test_eth_mtu) ... FAIL

Example:

781s FAIL: test_dhcp6 (__main__.TestNetworkd.test_dhcp6)
