Hello
I'm using kgdboe for a ppc based linux-2.6.11. The patches are from linux-2.6.13-kgdb-2.3.tar.
i am able to connect and use it. But sometimes i'm getting calltrace related to net_rx_action. Currently I have set breakpoints in ip_conntrack.ko and have added symbol file in my host machine.
After setting a few breakpoints and debugging :

Program received signal SIGSEGV, Segmentation fault.
