I've not followed this. You said that tgtd works if you configure by hand but it doesn't if you use targets.conf, right? If so, please find out how commands to set up targets are different. Anyway, your log (2009/10/28) says that the medium changer driver crashes during READ_ELEMENT_STATUS due to some memory issue. Looks like smc doesn't check memory overwrite.
