Heute haben die Experten mal wieder raus gefunden, warum was nicht klappt. Für die LAN-Schnittstelle fehlt im Manjaro Build ein Kernel Modul.
Dan vom Manjaro Team hat daraufhin einen neuen Kernel gebaut, der wurde von meinem System auch ordentlich geladen usw.
pacman -Syu
Kernel-Version
[root@quartz64 modules-load.d]# uname -a
Linux quartz64 5.13.0-rc4-0.5-next-20210603-MANJARO-ARM #1 SMP PREEMPT Sat Jul 3 15:34:57 UTC 2021 aarch64 GNU/Linux
Danach neugestartet, aber nix? Nachdenken.....
lsmod
Kein motorcomm (so heißt das Modul) zu finden. Dann in /etc/modules-load.d ein File angelegt mit Namen net.conf
Inhalt des Files
motorcomm
Neustart, danach
[root@quartz64 modules-load.d]# lsmod
