Okay I was able to reproduce the problem with Trusty open-iscsi package:

Good news,
I just backported tgtd from upstream (in the same PPA) and the
following sequence:
root@hertz:~# tgtd

panics:

The issue you linked below is one of the problems we identified (iSER discovery

The other issue is that we are getting very poor iSER Random I/O throughput and

Hadar,
This is probably not going to happen.
Back-porting entire upstream versions to stable releases, to fix an
issue, is not accepted by Ubuntu community.
Based on the following public discussion:
https://groups.google.com/forum/#!msg/open-
iscsi/BP6Q33U3ZIY/HlZOO54XV1UJ
It looks like there
Rafael, Brian,
I would like to send you an IB HW.
Please write here your address and other relevant details and I'll send
you Mellanox HCA with IB support.
Thanks,
Hadar

1. The compatibility issue is:
error occurred during discovery from the initiator
The log messages at the initiator gives following messages:

I need more information on this. Since I don't have the HW to test iSER,
I really need people interested on this bug to describe what patches are
missing from upstream code (into Trusty's version) and what kind of
compatibility issues they are facing.
Thank you
