With neither ACPI MADT nor an MP-table the kernel has no way of knowing about any I/O-APIC. You do have UP_IOAPIC enabled, so the kernel should look for it. Please check your BIOS settings, and try with no ACPI at all in the kernel (just to verify that acpi=off doesn't prevent MP-table parsing). /Mikael |
