In particular, if your ACPI tables have the information, you should have seen something like this: .. ACPI: Local APIC address 0xfee00000 ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled) Processor #0 15:2 APIC version 20 ACPI: LAPIC (acpi_id[0x01] lapic_id[0x01] enabled) Processor #1 15:2 APIC version 20 ACPI: LAPIC_NMI (acpi_id[0x00] polarity[0x1] trigger[0x1] lint[0x1]) ACPI: LAPIC_NMI (acpi_id[0x01] polarity[0x1] trigger[0x1] lint[0x1]) ACPI: IOAPIC (id[0x02] address[0xfec00000] global_irq_base[0x0]) ... and you shouldn't ever have gotten to the SMP table parsing, because the kernel doesn't need the information. However, your dmesg doesn't have that. Which means that either you don't have the proper ACPI tables, or you don't ave CONFIG_ACPI_BOOT set. Your .config file says you _do_ have CONFIG_ACPI_BOOT set, which would imply that your BIOS tables really _are_ UP-only, even for ACPI. Did they actually sell you the thing as being HT-enabled? It doesn't look like it is..
