Manjaro Image - LAN Schnittstelle

[FrankM]

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

Funktioniert!

Problem ist mittlerweile gefixt.

Ab dieser Kernelversion wird das Modul automatisch geladen, es ist im Kernel eingebaut.

@frankm

and in 5.13.0-rc4-0.8 you have to do it again

nice tips i got the board working
