[Eisfair] Fehler nach eisfair-update, eisfair fährt gleich wieder runter, libkmod: kmod_module_new_from_loaded: could not open /proc/modules: No such file or directory

Mi Aug 24 12:39:33 CEST 2022

Hallo Zusammen,

nachdem ich einige Updates für meinen virtuellen eis64-virt 4.19.245 
(old) / 4.9.255 unter Xen gemacht habe, fährt er nicht mehr hoch, 
sondern wieder herunter.

Folgende Bildschirmausgaben sind zu sehen:

So wie ich das sehe, findet er jetzt irgendwelche Kernelmodule nicht und

Wie kann ich diesen Fehler abstellen? Hat Jemand eine Idee?
