- Machine-check exception (MCE, doslova výjimka kontroly stroje, volně chyba v procesoru) je označení pro typ hardwarových chyb a jejich ohlášení centrální procesorovou jednotkou. Jedná se typicky o chyby v samotném procesoru, na , v procesorové mezipaměti nebo v operační paměti. Nejedná se o chybu způsobenou softwarem, ale selhání hardwaru – typickými příčinami bývá selhání , často v důsledku přehřátí (kvůli selhání chlazení počítače) nebo přetaktování. Výjimka MCE je dostupná na procesorech rodiny Pentium a procesorech kompatibilních. V rámci tabulky vektorů přerušení v chráněném režimu má přidělenu pozici 18. (cs)
- A machine-check exception (MCE) is a type of computer hardware error that occurs when a computer's central processing unit detects a hardware error in the processor itself, the memory, the I/O devices, or on the system bus; in some architectures, an MCE only occurs for an unrecoverable error. On x86 architectures, a machine-check exception is not caused by software. However, on other architectures such as PowerPC, certain software bugs such as invalid memory accesses can cause machine-check exceptions. The error usually occurs due to component failure or the overheating or overclocking of hardware components. Most machine-check exceptions halt the operating system and require a restart before users can continue normal operation. Diagnosing the failure can be often difficult because so little information about what caused the problem is captured during the error. Modern versions of Microsoft Windows on IA-32 and x86-64 processors handle machine-check exceptions through the Windows Hardware Error Architecture. When WHEA detects an uncorrectable machine check exception, it displays the error in a Blue Screen of Death, with the following parameters (which vary, but the first parameter is always 0x0 for a machine check exception): *** STOP: 0x00000124 (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000) Older versions of Windows handle similar exceptions through the Machine Check Architecture. In this case, the Blue Screen of Death will show an error similar to the following: STOP: 0x0000009C (0x00000030, 0x00000002, 0x00000001, 0x80003CBA) On Linux, a process (such as klogd) writes a message to the kernel log and/or the console screen (usually only to the console when the error is non-recoverable and the machine crashes as a result): CPU 0: Machine Check Exception: 0000000000000004Bank 2: f200200000000863Kernel panic: CPU context corrupt (en)
- 机器检查异常（英語：Machine Check Exception，简称MCE）是计算机的中央处理器检测到一个硬件问题发生的计算机硬件错误。 现代版本的Microsoft Windows通过处理机器检查异常。当该架构检测到机器检查异常（MCE）时，它会以蓝屏死机显示该错误，附以下列参数（数值可能变化，但机器检查异常导致的首个参数始终为0x0）： *** STOP: 0x00000124 (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000) 在Linux上，进程（例如klogd）会向内核日志和/或控制台屏幕写入消息（通常仅在错误不可恢复且机器因此崩溃时，消息才会发送到控制台）： CPU 0: Machine Check Exception: 0000000000000004Bank 2: f200200000000863Kernel panic: CPU context corrupt 该错误通常是由于硬件组件的故障或过负载而发生，其中的错误不能用更具体的错误消息来识别。诊断其错误消息可能很困难，尽管英特尔奔騰处理器确实生成更具体的代码，可以联系制造商进行解码。 大多数机器检查异常需要重启系统才能继续为用户正常运行。 (zh)
