I believe that Intel say the steppings should match. Can you swap one of the CPUs out from another box? Not sure if using microcode.ctl would help, but probably worth doing anyway (we run it on all our productions boxes).

Intel's line on older processor lines were that the steppings shouldn't differ by more than 1, Intel's 5400 series datasheet says: http://www.intel.com/Assets/en_US/PDF/datasheet/318589.pdf Not all operating systems can support dual processors with mixed frequencies. Mixing processors of different steppings but the same model (as per CPUID instruction) is supported. Details regarding the CPUID instruction are provided in the AP-485 Intel® Processor Identification and the CPUID Instruction application note. but OTOH, it seems that mixing both settings of L5420 caused some trouble on Intel S5000 boards before they updated the BIOS... http://downloadmirror.intel.com/18075/eng/release.txt Cheers, Tim. ___ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
