I compiled a 2.6.8-rc3 kernel with ACPI and LAPIC support. In dmesg I find: ...... Local APIC disabled by BIOS -- reenabling. Found and enabled local APIC! ...... ACPI: Using PIC for interrupt routing ACPI: PCI Interrupt Link [LNKA] (IRQs 3 4 5 6 7 9 *10 11) ACPI: PCI Interrupt Link [LNKB] (IRQs *3 4 5 6 7 9 10 11) ...... Is something wrong with my local APIC ? Why ACPI is still using PIC instead of LAPIC ?
