I discovered that you need the 'CPU Enumeration' part of ACPI to be enabled otherwise the kernel only sees physical processors, not sibling HT processors - shouldnt this be selected automatically when you select SMP ? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
