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.
