Here's a summary of what I encountered (all this can be found in the "SMP problems with -CURRENT (and BETA5)": With HTT enabled in the BIOS: 1) With ACPI and APIC enabled: Locking up after detecting my hard drives and launching the second processor. 2) With ACPI disabled and APIC enabled: Crashing with a "Fatal trap 9". 3) With both ACPI and APIC disabled: Success. With HTT disabled in the BIOS: 1) With ACPI and APIC enabled: Locking up after detecting my hard drives. And, I'd agree with your assesment that, no matter the cause, this is a pretty significant show-stopping bug :-) Adam
