I was able to reproduce the issue. I'm guessing you're using a wired
ethernet with no explicitly saved connection profile? When NM
auto-creates an ephemeral connection profile, it gets an equally
ephemeral UUID. The RFC7217 implementation in NM derives the UUID from
the connection profile (amongst other things), which means the results
of the algorithm - the IID - isn't stable at all.

You can work around this by saving the connection profile, e.g.:
$ nmcli con edit 'Wired connection 1' # the name might be localised
nmcli> save
Alternatively, if you don't want RFC7212 addresses at all and prefer
the previous behaviour, you can do:
nmcli> set ipv6.addr-gen-mode eui64
This worked for me perfectly, and restored the old behavor so I get an
EUI64 address. Thanks!
