The BIOS toggle just changes the HT CPUs to be listed as disabled in the MADT table ACPI uses. The 'Hyperthreading' printf in the dmesg is based on reading the registers from the CPU and is output even in a UP kernel. Your MP table looks ok as well, so I'm not sure why a dmesg with no ACPI is not finding your CPUs. How did you disable ACPI, did you boot using safe mode? If so, try breaking into the loader and just disable ACPI via set hint.acpi.0.disabled=1 Safe mode disables SMP support as well as ACPI. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
