Intel的奔腾-M处理器可以说是他们的用心之作，从该处理器出现的错误数量就可以看出来。目前，奔腾-M处理器只有14个已经确定的错误，对比一下，奔腾4处理器具有73个以上，奔腾3具有83个以上，奔腾2具有92个，奔腾具有72个。下面就是奔腾-M处理器的错误列表（原文）：

Performance Monitoring Event that counts Intel Thermal Monitor 2 transitions (59h) is not accurate；

Performance Monitoring Event that counts the number of instructions decoded (D0h) is not accurate；

RDTSC Instruction may report the wrong time stamp counter value；

Code Segment limit violation may occur on 4GB limit check；

FST Instruction with Numeric and Null Segment Exceptions may cause General Protection Faults to be Missed and FP Linear Address (FLA) Mismatch；

Code Segment is wrong on SMM Handler when SMBASE is not aligned；

IFU/BSU Deadlock may cause system hang；

Processor can enter a livelock condition under certain conditions when FP exception is pending；

Write Cycle of Write Combining Memory Type does not Self Snoop；

Performance Monitoring Event that counts Floating Point Computational Exceptions (11h) is not accurate；

Inconsistent Reporting of Data Breakpoints on FP (MMX) loads；

Code Breakpoint may be taken after POP SS instruction if it is followed by an instruction that faults；

SysEnter and SysExit instructions may write incorrect Requestor Privilege Level (RPL) in the FP Code Segment selector (FCS)；

Memory Aliasing with Inconsistent A and D Bits may cause Processor Deadlock。

目前Intel还没有相应的修正计划，实际错误数量还有待进一步考察。
