Is netconsole an option, if ethernet is available? If it has a serial port, use another system as a serial console? (I admit not knowing how well "console on a USB serial port" works - if it does, that may be an option) [-- Attachment #1.2: Type: application/pgp-signature, Size: 832 bytes --] [-- Attachment #2: Type: text/plain, Size: 170 bytes --] _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies ^ permalink raw reply [flat|nested] 4+ messages in thread

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?

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.
