Hm, and in your dmesg I see that you have the situation that I described: your CPU is supposedly dual-core (and supports HTT on top of that), but FreeBSD for some reason [*] sees only one cpu, e.g.: > cpu0: <ACPI CPU> on acpi0 So I am quite sure that the patch that I posted should help you. [*] - yes, I do want to see your *verbose* dmesg from the working kernel. -- Andriy Gapon
