[First posting, please don't eat me :-)] I'm using kernel 2.4.2 and have never been able to shutdown my machine by software. Neither 2.2.x nor 2.4.x, with and without Real Mode power off. Bios is broken, no acpi tables can be found: ACPI-0191: *** Warning: Invalid table signature found ACPI-0073: *** Error: Acpi_load_tables: Could not load RSDT: AE_BAD_SIGNATURE ACPI-0101: *** Error: Acpi_load_tables: Could not load tables: AE_BAD_SIGNAT ACPI: System description table load failed I tried with ACPI only, APM only and using both. Real Mode power down reboots the machine and "normal" power down just crashes (register dump ...). I read about patches, which fake ACPI tables, and some others which power down in real mode in a different way(?), but couldn't apply them because of different kernel versions.
