dmesgIn meiner Ausgabe werden einige merkwürdige Fehler im Zusammenhang mit der Bereitstellung sda4beim Booten angezeigt. Dabei handelt es sich um eine erweiterte Partition, die verwendete logische Datenträger enthält.
Nachfolgend sehen Sie einen Auszug meiner dmesgAusgabe kurz nach dem Booten. Ich habe [UFW BLOCK]zwischendurch allerdings einige Firewall-Einträge entfernt.

Antwort1
Das ist vielleicht spät, aber ich habe einen Debian-Fehler gefunden:https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794849
Es sieht so aus, als ob os-prober das Problem ist und es läuft, wenn ein neuer Kernel installiert wird. Ich habe gerade ein Update auf einem System getestet, das diese Einträge vor dem Update nicht in der dmesg-Ausgabe hatte, danach aber auftauchte.
