Hi Andrey, Can you help post some good/still relevant links? Call me stupid, I did google, found a few websites, and most of them are kind of out of contexts(don't know how to follow). For beginners, step-by-step tutorials are the best. so far, sounds like kgdb is promising, but it requires a lot of backgrounds to start with. I still have not figured out the exact steps.

You'd better budget some time to google a bit and watch conference videos showing debugging techniques :) There are fine videos from past Kernel Recipes conferences.

What are some widely used industrial tools (software/ hardware) for debugging Linux kernel and driver? Recently my company allocate a budget for purchasing this kind of tools, so I would like what are the tools that would greatly ease our development.

Hi, I'm trying to build the latest version of kernel. i followed steps on this link https://kernelnewbies.org/KernelBuild .I switched to branch v4.9-rc9 when I check my current branch using command (git status), I get ( On branch v4.9-rc9 ) .when I complete next steps on the page and open .conf file .I find # Linux/x86 4.9.0-rc5 Kernel Configuration . why isn't it # Linux/x86 4.9.0-rc9 Kernel Configuration ?

Hi Valdis, Thanks for your prompt answer. I have ext3 builtin the kernel. After looking into the code I found that sys_mknod function fails. I am unable to understand why this happens? Regards,Amit.
