Hi Kernel mailing list! IIRC: if I recall correctly we couldn't compile ACPI without Power management option (CONFIG_PM), but now, this is possible. If the answer to the subject is no, then consider apply this patch on kernel 2.4.26. Accidentally, I compile ACPI without CONFIG_PM on one Dell something dual Pentium III and power off didn't work. So I need some confirmation from acpi-devel, but this is one meter of xconfig of the kernel so ... For APM Xconfiguration, it's better that, we can choose APM options only if we select APM ( because if we don't select CONFIG_PM, CONFIG_APM will be disable and the APM options don't!). This patch correct also this situation. Thanks, -- Sérgio M. B.
