 Its in azalia_codec_comresp() apparently.
 
 
 
 	DPRINTF(("%s: information of codec[%d] follows:\n",
 	    XNAME(this->az), addr));
  return -1;
 	/* codec vendor/device/revision */
 	err = this->comresp(this, CORB_NID_ROOT, CORB_GET_PARAMETER,
 	    COP_REVISION_ID, &rev);
 	if (err)
 		return err;
  return -1;
 
 
 With the first "return -1" the system boots, with the second it hangs.
