hallo, ich wollte eigentlich mal schauen, was powertop bei mir so anzeigt. dafür musste ich ein paar Kernel-acpi Optionen aktivieren (cpu freq uÄ) Seitdem geht mein aufs nicht mehr zu mounten:
Code:

kann damit jemand was anfangen? Bevor ich die acpi-sachen aktiviert habe gings wunderbar. Kann das wirklich irgendwie zusammenhängen?
Mein Kernel: 2.6.33-zen1

Schöne Grüße
Christian

ja, das zen experimentell ist, ist schon klar. hatte nur gedacht, dass vielleicht das problem wo anders her kommt und deswegen bekannt ist, oder das es einer der anderen zen-user kennt (ich bin ja erst über das Forum hier auf zen gestoßen). Aber da es mit dem letzten zen-kernel vor den neuen acpi-optionen ging, werd ich einfach den von vorher nehmen.

Schöne Grüße
Christian

EDIT: aufs nicht als modul, sondern in den kernel hat geholfen
