Looks like you loaded ens137x.c and then that driver got unloaded leaving the callback still valid, then the core timer code decided to walk off a cliff using that pointer.
0xc0365322 is in snd_timer_free (sound/core/timer.c:676). 671 static int snd_timer_free(snd_timer_t *timer) 672 { 673 snd_assert(timer != NULL, return -ENXIO); 674 if (timer->private_free) 675 timer->private_free(timer); 676 snd_magic_kfree(timer); 677 return 0; 678 } The problem seems to be a sort of chicken/egg case? We can't rely on modules being around even with this inter dependency case.
