(someting like that: "kernel > /vmlinuz-2.6.10-2.1.ll.rhfc3.ccrma ro root=LABEL=/1 rhgb quiet apm=off > acpi=force") Same with me, I fixed the problem by adding append="acpi=force" to the Demudi-section of my /etc/lilo.conf. Before this, the kernel refused to automatically use ACPI because the BIOS was older than some specific date, although it has nominal ACPI support (I remember a log message like: "ACPI disabled by default because your BIOS is too old"). It's Demudi 1.2.0 and the default 2.4 kernel with its mm-patches. Jens
