Output of both commands attached…

Yes, unstable are old names, right
Some errors are reported for eth0 interface:
eth0: Policy *slot* yields "ens6f0".
eth0: Could not set AlternativeName= or apply AlternativeNamesPolicy=, ignoring: File exists
eth0: /usr/lib/udev/rules.d/80-net-setup-link.rules:11 NAME 'ens6f0'
eth0: /usr/lib/udev/rules.d/99-systemd.rules:68 RUN '/lib/systemd/systemd-sysctl --prefix=/net/ipv4/conf/$name --prefix=/net/ipv4/neigh/$name --prefix=/net/ipv6/conf/$name --prefix=/net/ipv6/neigh/$name'
eth0: sd-device: Created db file '/run/udev/data/n69' for '/devices/pci0000:00/0000:00:1c.0/0000:01:00.0/net/eth0'
ens6f0: Failed to rename network interface 69 from 'eth0' to 'ens6f0': File exists
The bug should be reassigned to udev.
Thank you very much for tip!
