Ok, I tried to do that, i don't know if I did right, my first time :)
I compiled the module emu10kx using "make COPTS=-g", enabled dumpdev and
dumpdir.
When the system boots i load the module with snd_emu10kx and it happens when
i try to do a sysctl -a command,

After reboot it saved the dump to /var/crash/vmdump.0, so i used kgdb
kernel.debug /var/crash/vmdump.0 and the command 'backtrace' on kgdb, let me
know if i did something wrong.
