Testing from iscsitarget trunk with the update for revision 470 (released Fri Apr 6 21:58:31 2012 UTC)
http://iscsitarget.svn.sourceforge.net/viewvc/iscsitarget?revision=478&view=revision It appears they have addressed this issue with the fix noted above. Obviously, this isn't included in the iscsitarget and iscsitarget-dkms packages in Ubuntu Precise currently. The issue notes there is a problem with kernel versions 3.2+ without the 478 fix in place. Testing so far seems to indicate this is fixed with that update.
