Hi, I am not able to catch the core dump either. My ulimit -c is set to unlimited and I dont see anything in /var/crash. Is a driver crash different from an app crash? How & do I need to find the core to debug at all? Thanks, Shivku On Wed, Jun 10, 2009 at 2:20 PM, Shiva Kumar<shivku@xxxxxxxxx> wrote: > Hi Nikolay, > No luck. Segmentation fault again.
