I did open bugzilla for my I/O hang problem and sent over some data. Hannes
is helping.

Sorry for the lack of update on this. When it is SLES it is harder for me
to debug, because I do not know what is in there.
Anthony (ccd here) hit a bug with the same kernel and uploaded the iscsi
files a couple weeks ago, and at first glance I did not see anything. I have
been meaning to dig deeper but have not had time.
Have you guys made a SUSE bugzilla? I am ccing Hannes over at Novell who
handles iscsi over there. Maybe he has seen it.

Hi folks,
I'm running a SLES 10 SP2 box and encountered a kernel bug during
iSCSI login process.
The kernel version I'm running is 2.6.16.60-0.21-smp, and the open-
iscsi I'm using is open-iscsi-2.0.707-0.44
I used two hosts and two eth ports on each. The two hosts have shared
access to the same volumes.
Multipath is used via Ifaces.

The problem is during reboot, kernel bug is seen while the initiator
tries to login to the targets.
here's some information at the scene:
