Hello.
If I'm not wrong, there was an issue, around Fedora 27 (or it was 28?)
where the MAC address of the wifi card was different upon each reboot.
The issue was solved in some kernel update (or uboot update? sorry, I
don't remember).
Now the issue is here again.
Raspberry Pi 3, Fedora 30, aarch64, kernel 5.1.2-300
Are you aware of that?
Thanks,
A.
