Embodiment Construction
[0019] The present invention, based on the kernel high-precision timer, reboot command and kernel monitoring module, firstly starts a kernel high-precision timer at the entrance of executing the reboot command (restart command), and at the end of the normal reset process, the CPU is controlled by the user mode application program Register to reset the Linux file system and record the reset reason log. If unsuccessful, call the default code of the reboot command to execute the Linux file system reset and record the reset reason log. When the kernel high-precision timer expires, the Linux file system is not reset successfully. In the kernel mode, the Linux file system is reset by directly controlling the CPU register, and various reset reasons are recorded to the system log file. The dual protection of user space and kernel space can maximize the reliability of the reboot command to complete the restart. In the case that the Linux file system is damaged and the reboot command cann...
