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 AMD64 Processors 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 Arguments: Arg1: 00000000 Arg2: 8054da70 Arg3: c4024000 Arg4: 00000136 Debugging Details: ------------------ BUGCHECK_STR: 0x9C_IA32_AuthenticAMD CUSTOMER_CRASH_COUNT: 1 DEFAULT_BUCKET_ID: DRIVER_FAULT LAST_CONTROL_TRANSFER: from 806f28df to 805339ae SYMBOL_ON_RAW_STACK: 1 STACK_TEXT: 8054da48 806f28df 0000009c 00000000 8054da70 nt!KeBugCheckEx+0x1b 8054db74 806edc2e 80042000 00000000 00000000 hal!HalpGetFeatureBits+0x75 00000000 00000000 00000000 00000000 00000000 hal!HalpWriteCmosTime+0xaa STACK_COMMAND: dds @$csp ; kb FOLLOWUP_IP: nt!KdPitchDebugger+ef4 8054da70 0100 add [eax],eax FOLLOWUP_NAME: MachineOwner SYMBOL_NAME: nt!KdPitchDebugger+ef4 MODULE_NAME: nt IMAGE_NAME: ntoskrnl.exe DEBUG_FLR_IMAGE_TIMESTAMP: 41108004 FAILURE_BUCKET_ID: 0x9C_IA32_AuthenticAMD_nt!KdPitchDebugger+ef4 BUCKET_ID: 0x9C_IA32_AuthenticAMD_nt!KdPitchDebugger+ef4 Followup: MachineOwner ---------
