Hi,

========

While loading sample ethernet driver (devnp-sam.so) via io-pkt-v4 command it throws an error.

command:
======

io-pkt-v4 -d /lib/dll/devnp-pe.so

Error
====

Nov 09 17:26:14    5    14     0 tcpip starting
Nov 09 17:26:14    3    14     0 Using pseudo random generator.  See "random" option
Nov 09 17:26:14    5    21     0 run fault pid 892961 tid 2 signal 11 code 1 ip 0x80854b8 sbin/io-pkt-v4

Time to fire up gdb.

Indeed.  Before you start io-pkt ensure that
dumper is running.

After the fault occurs, look in /var/dumps/
for a file that looks like io-pkt-v4.core.

You can then run:

# gdb /sbin/io-pkt-v4 /var/dumps/io-pkt-v4.core

Hint #1:  compile your driver with "-g -O0" to make
the backtrace MUCH more helpful.

Hint #2: learn about a file called ~/.gdbinit

Don't forget to turn off the sigsegv handler!!!!!

(-S option to io-pkt)

You don't really need to - I never bother, anyways.

Just skip the first couple of frames in the 
offending thread, which is the sigsegv handler.
