It seems that your BIOS makes it a condition that OS supports the following feature: ACPI_CAP_C1_IO_HALT. FreeBSD doesn't really support it, but you can try adding it to 'features' variable in acpi_cpu_attach() in function in sys/dev/acpica/acpi_cpu.c; look for the following line: sc->cpu_features = ACPI_CAP_SMP_SAME | ACPI_CAP_SMP_SAME_C3; I don't think that should break anything for you, but may improve a thing or two. I'd interested in seeing acpidump -d -t produced after the patching. Thank you. -- Andriy Gapon
