Hi Saket, You may configure kdump and use crash utility for debugging offline. Here are some useful links. https://sites.google.com/site/syscookbook/rhel/rhel-kdump-rhel6 http://www.novell.com/support/kb/doc.php?id=3374462 Otherwise systemtap is good option too. http://www.linuxforu.com/2010/09/systemtap-tutorial-part-1/ Thanks, Chaitanya On Tue, Aug 6, 2013 at 3:55 PM, Saket Sinha <saket.sinha89@gmail.com> wrote:

I am facing an issue where I have been developing a filesystem driver(over x86) which has become "unstable" by which I mean , at compile time it is building but during runtime it fails when I call the corresponding APIs from the user-space.

In order to find out exactly where it is failing, I need to debug the driver. I am very new to kernel development. I have heard about KGDB and KDB but it takes quite a lot to get them working so waht are the other tools available?
