Description Dave Hodgins 2023-06-20 06:43:21 CEST 
In a Mageia 9 i586 vb guest, I noticed a kernel-user-after free in the journal.
Also, it does not get it's ipv6 address. From "ip addr" ...
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 08:00:27:78:ac:dc brd ff:ff:ff:ff:ff:ff
    inet 192.168.10.123/24 brd 192.168.10.255 scope global enp0s3
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:27ff:fe78:acdc/64 scope link 
       valid_lft forever preferred_lft forever

In a Mageia 9 x86_64 guest "ip addr" shows a valid address starting with 2607
in addition to the above.
