ACPI with CPU enumeration is enabled, but the sibling CPUs aren't activated.
This is all what I have of the boot message (standard buffer size is too small, apparently):
CPU: After all inits, caps: 3febfbff 00000000 00000000 00000080 Intel machine check architecture supported. Intel machine check reporting enabled on CPU#3. CPU#3: Intel P4/Xeon Extended MCE MSRs (12) available CPU#3: Thermal monitoring enabled CPU3: Intel(R) Xeon(TM) CPU 1.40GHz stepping 01 Total of 4 processors activated (11034.62 BogoMIPS). WARNING: No sibling found for CPU 0. WARNING: No sibling found for CPU 1. WARNING: No sibling found for CPU 2. WARNING: No sibling found for CPU 3.
Recent 2.4.x kernels (starting with 2.4.20 IIRC) support Hyperthreading on this machine (Siemens Primergy H450). - 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/
