Das Problem tritt in Gentoo, Void und anderen Distributionen auf, die zRAM unterst\u00fctzen und Pakete mit neuen Kernelversionen anbieten.    <\/p>\n<p>Die Ursache des Fehlers ist eine \u00c4nderung im Kernel 6.12, die es erm\u00f6glicht, die Kompressionsalgorithmen w\u00e4hrend des Betriebs anzupassen. Gleichzeitig wurde in Kconfig die Logik zur Auswahl der verf\u00fcgbaren Kompressionsalgorithmen w\u00e4hrend des Kernels-Baus ge\u00e4ndert. Diese \u00c4nderung f\u00fchrte zu Problemen in Distributionen, die sich auf die Standardeinstellungen verlassen haben und nicht alle verf\u00fcgbaren zRAM-Algorithmen in der Kconfig f\u00fcr den Kernel 6.12 einzeln aktiviert haben.     <\/p>\n<p>Nach dem Update auf Kernel 6.12 war in \u00e4hnlichen Distributionen nur der standardm\u00e4\u00dfig festgelegte Basis-Kompressionsalgorithmus ausw\u00e4hlbar, und nicht alle unterst\u00fctzten Algorithmen. Folglich kam es beim Versuch, in zRAM Algorithmen zu aktivieren, die nicht mit dem Standardalgorithmus \u00fcbereinstimmten, beim Booten zu einem Abbruch. Beispielsweise trat beim Ausw\u00e4hlen des Algorithmus lz4 der Fehler \u201ezramctl: \/dev\/zram0: failed to set algorithm: Invalid argument\u201c auf, da nur die Unterst\u00fctzung f\u00fcr lzo \u00fcbrig blieb, statt der zuvor unterst\u00fctzten Algorithmen lzo, lz4, lz4hc, 842 und zstd.    <\/p>\n<p>Das Problem wird gel\u00f6st, indem jeder Kompressions-Backend in Kconfig einzeln aktiviert wird (die Einstellungen CONFIG_ZRAM_BACKEND_* wurden im Kernel 6.12 hinzugef\u00fcgt): CONFIG_ZRAM_BACKEND_LZ4=y CONFIG_ZRAM_BACKEND_LZ4HC=y CONFIG_ZRAM_BACKEND_ZSTD=y CONFIG_ZRAM_BACKEND_842=y
