do you see the LED blinking?
if yes, you could see a last kernel dieing message in the log terminal
(often alt+F10 in linux console).  try to switch to that one quickly
after loading the module, and wait for the death.  if sysrq is enabled
in the kernel, you can see even the backtrace via alt+sysrq+P.
