. However, when the process is in the kernel state and holds the lock, killing the process will cause the system to deadlock. Deadlocks are more difficult to handle than panic, so the kernel chooses panic when a machine check occurs in a kernel-state process.In the newly written handler, a lock-free binary log file system is created, which is completely separate from the PRINTK log file. It logs the machine check into a buffer, and when the buffer is full, the subsequent information is discarded
Mce-inject function
Mce-inject is used to test whether the Mcelog can obtain the correct hardware error information and decode correctly, Mce-inject may inject the specified error message to the kernel, so it is easy to understand the function of Mcelog is normal.It is important to note that when the user uses the Mce
Recently, when I was working on a real estate project, I used the text editor tiny mce. Due to JavaScript verification, I began to study tiny mce.

So I posted my solution for reference by friends who encountered

A little understanding of Linux under MCE (Machine Check Exception)
1.MCE (Machine Check Exception) is a logging mechanism used to report host hardware-related issues.
The log file for the 2.MCE (Machine Check Exception) is/var/log/mcelog
3. The mcelog does not necessarily exist on any Linux host. Only if there is a hardware error, there will be/var/log/mce
On the old Intel processor, when the hardware detects an error, it broadcasts a MCE to each logical CPU of the system. This design is because of hardware flaws, because the original processor found an error (such as a memory error), it will flow with pipeline to any unpredictable CPU, resulting in system problems. Based on this hardware design problem, the strategy of broadcasting MCE to all CPUs of the who
