Although the local APIC is detected, it doesn't get used. (dmesg appended below). 2. When local APIC is enabled, then the poweroff doesn't actually poweroff... e.g. shutdpown -h leaves the fan spinning, and presumably other things wit hpower as well. Anyone know why 1. PIC is used instead of APIC? 2. Why no power off? Are these due to the ACPI errors indicated in the dmeag output? TIA Hamish Marson., DMI present. IBM machine detected.
