MACHINE_CHECK_EXCEPTION (9c)
A fatal Machine Check Exception has occurred.
KeBugCheckEx parameters;
    x86 Processors
        If the processor has ONLY MCE feature available (For example Intel
        Pentium), the parameters are:
        1 - Low  32 bits of P5_MC_TYPE MSR
        2 - Address of MCA_EXCEPTION structure
        3 - High 32 bits of P5_MC_ADDR MSR
        4 - Low  32 bits of P5_MC_ADDR MSR
        If the processor also has MCA feature available (For example Intel
        Pentium Pro), the parameters are:
        1 - Bank number
        2 - Address of MCA_EXCEPTION structure
        3 - High 32 bits of MCi_STATUS MSR for the MCA bank that had the error
        4 - Low  32 bits of MCi_STATUS MSR for the MCA bank that had the error
    IA64 Processors
        1 - Bugcheck Type
            1 - MCA_ASSERT
            2 - MCA_GET_STATEINFO
                SAL returned an error for SAL_GET_STATEINFO while processing MCA.
            3 - MCA_CLEAR_STATEINFO
                SAL returned an error for SAL_CLEAR_STATEINFO while processing MCA.
            4 - MCA_FATAL
                FW reported a fatal MCA.
            5 - MCA_NONFATAL
                SAL reported a recoverable MCA and we don't support currently
                support recovery or SAL generated an MCA and then couldn't
                produce an error record.
            0xB - INIT_ASSERT
            0xC - INIT_GET_STATEINFO
                  SAL returned an error for SAL_GET_STATEINFO while processing INIT event.
            0xD - INIT_CLEAR_STATEINFO
                  SAL returned an error for SAL_CLEAR_STATEINFO while processing INIT event.
            0xE - INIT_FATAL
                  Not used.
        2 - Address of log
        3 - Size of log
        4 - Error code in the case of x_GET_STATEINFO or x_CLEAR_STATEINFO
