I installed a new 19.04, which came with kernel -13. I ran the same tests as before, and did not see any problem. Please see my complete log below for a replay.

Title:
OSA/qeth inconsistent interface names
Status in Ubuntu on IBM z Systems:
Confirmed
Status in s390-tools package in Ubuntu:
New
Bug description:
After doing an installation of an s390x system with disco where OSA
devices are in use (means LPAR and z/VM) the device name of the
default interface that is generated during the installation is file,
for example:
ubuntu at s1lp15:~$ lszdev qeth | grep yes
qeth 0.0.c000:0.0.c001:0.0.c002 yes yes encc000
If another device is created (e.g. with the help of: sudo chzdev -e
c003), it name is no longer based on the address, but it get's an
'eth?' name:
ubuntu at s1lp15:~$ lszdev qeth | grep yes
qeth 0.0.c000:0.0.c001:0.0.c002 yes yes encc000
qeth 0.0.c003:0.0.c004:0.0.c005 yes yes eth0
The coressponding 'ip a' line is:
9: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
(02:29:22 PM) jfh: link/ether 5a:2e:d8:c6:c1:03 brd ff:ff:ff:ff:ff:ff
After a 'sudo systemctl restart systemd-udev-trigger.service' it get's the correct name 'encc003':
9: encc003: <BROADCAST,MULTICAST>
