Danke für die Info. "dmesg" auf dem ODROID geht jetzt nicht mehr - habe das Gerät erneut retour geschickt, um Gutschrift gebeten und mir unabhängig davon einen Raspberry Pi 2 besorgt.
Der läuft nun schon wieder einige Tage völlig unauffällig unter Raspbian.
Nachfolgend trotzdem mal aktuelle Ausgabe von dmesg auf dem Pi2.
Stick und LNB sind ja noch die selben. Vielleicht gibt es ja Hinweise?
