iscsi-target 1.4.20 is an out-of-tree kernel module. So reporting the
problem to linux-scsi doesn't help. Use
iscsitarget-devel@lists.sourceforge.net instead.

You confuse two different iSCSI implementations. Seems that Ubuntu
supports two different implementations:

iscsitarget.sourceforge.net
stgt.sourceforge.net

The log says that you use the former. If you use the latter and hit a
problem, please report it to stgt@vger.kernel.org.
