As to the steps after prepearing vmlinux for debug: I also find the following important link: https://github.com/AltraMayor/XIA-for-Linux/wiki/Debugging-the-Linux-kernel But it seems that the kernel debugging metod described there is quite complex (qeuires virtualbox , nfs shared folder). I just wander if this is the method which is recommended & used for kernel module debugging. > Are you interested in debugging a kernel crash core? or use some of the kernel trace/probes to examine a running kernel? > I am intereseted in debugging a new kernel module which I will write (v4l pci express module) Regards, Ran
