#65034 — Bug#939328: linux-image-4.19.0-5-amd64: buster and stretch-backports kernel causes interfaces rename back to ethX on HPe DL360g10

Package: src:linux
Version: 4.19.37-5+deb10u2
Severity: normal

Hi,
installing the latest update caused our NICs to be renamed from "enoX" back to "ethX". We first experienced
this issue on Debian/buster on HPe DL360g10 and now found the same issue with the latest upload of the same
kernel to stretch-backports.

We're now working around this issue by using
$ cat /etc/systemd/network/101-onboard-rd.link 
[Link]
NamePolicy=onboard kernel database slot path
MACAddressPolicy=none


That said on a system still running Debian/stretch with the old working kernel, without
the systemd workaround applied I've the following:

svenhoexter@docker-018:~$ uname -a
Linux docker-018 4.19.0-0.bpo.5-amd64 #1 SMP Debian 4.19.37-4~bpo9+1 (2019-06-19) x86_64 GNU/Linux

On a system with the new kernel and the applied workaround we've:
