Please answer yes or no: ACPI enabled but APIC disabled works 100%? Safe mode disables both ACPI and APIC so it's not a good test of where the problem is. You should probably also test with ACPI disabled but APIC enabled ("set hint.acpi.0.disabled=1"). The APIC code has two methods of enumerating PIC devices: ACPI and MP table. With ACPI enabled, the APIC code gets its info from the MADT table. With ACPI disabled, it uses the MP table. Many older (< 2001) systems have problems with their MADT but an ok MP table. I think there are a few systems that have a correct MADT but flawed MP table but that is rare. Thanks, -- Nate
