Are these kernel.org/open-iscsi.org open-iscsi tools ir distro build ones?

I think this is due to a sysfs issue. If I am right it should be fixed 
in 872 
(http://kernel.org/pub/linux/kernel/people/mnc/open-iscsi/releases/open-iscsi-2.0-872.tar.gz) 
or I think you can change the SYSFS DEPRECIATED and SYSFS V2 DEPRECIATED 
settings. I cannot remember if you need to turn it on or off (I think 
you need to turn it on with older tools). Send your .config.

Also could you send the log messages for when it fails? And does normal 
login work? If you just boot from a local drive and run iscsiadm to 
login does it fail? What is the error message and what is the 
/var/log/message output?
