•处理:内核通常会打印错误信息和内核调用栈到系统日志中,这有助于开发人员诊断和修复问题。 1.2 Kernel Crash •定义:Kernel Crash 指的是内核因为严重错误而完全失去功能的情况。它可能是由 Oops 导致的,也可能是由硬件故障、驱动程序错误或其他严重的内核级别问题引起的。 •影响:当内核崩溃时,系统通常无法继...
There is also a good source-level kernel debugger called kgdb that supports the 2.4 and 2.6 kernels. KDB is invoked when a breakpoint is hit, the system panics or by the break key. The main point entry for KDB is kdb() in kdb/kdbmain.c; when invoked., KDB disables interrupts for ...

Specify the COM port number (note that VMWare creates COM2 by default) and the pipe you have created on the last page of the Kernel Module Wizard. It is also recommended to select 115200 as the connection speed: Note that debugging the target via COM port could be very slow. We recommen...
Debugging the kernel is not necessarily rocket science; in fact it can be achieved using very simple and straight forward techniques and some time, patience and perseverance. This page describes some tricks and techniques to help debug the kernel. ...
