Yes, it's now working well on my test environment. I built a rpm for
the patched kernel by myself. Well, you also need to stop default iscsi-initiator
service which is enabled by iscsi-initiator-utils. (/etc/init.d/iscsi stop)
Try attached my simple rpm spec file and here is a quick procedure.
1. download tarball open-iscsi-2.0-871.tar.gz from www.open-iscsi.org
2. build open-scsi rpm package with attached spec file
3. uninstall iscsi-initiator-utils package
4. install open-iscsi-2.0-871_xxxx and start initiator by /etc/init.d/open-iscsi start
