That would be me. 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 :-)
