ok, good debugging !
This is Debian-related and means that the initrd of the iscsi_2_6 
boot-image for
Debian is missing libraries needed to resolve user-id's into user-names.
The iscsid is trying to resolve the uid 0 to a username which failed because
it cannot find the uid-to-name resolving libs on the initrd.
For redhat- and suse-based systems these libs are called libnss_compat 
and libnss_files.
Could you please check on the iscsi_2_6 initrd on your Debian system if you
have these libs ? If not, could you add them and try again ?
