I want to double check I'm with you - so when you said that iser didn't 
work e.g "TCP worked very well. I've also updated from git to latest 
2.0.872 (latest change 2011-11-01) for testing. TCP always worked and 
iSER was always unusable." you actually wanted to say "iser from ofed" 
and not iser from this or that upstream kernel?

as life, mainline isn't perfect, but it doesn't say that ofed is perfect 
nor that by any bit its better then mainline, you may know and if you 
don't here are the news: the ofa community has to decided to stop 
producing ofed in the way it was done over the years, namely from now 
(Jan 2012) and onward, ofed will be only backports provided from 
mainline, no additions, so this false betterness claim can't even be 
stated anymore. Now, even this "backporting only" new mode has to be 
defined - since for example, is the iscsi case... except for iser, ofed 
will not provide the iscsi modules nor tools, so its not clear/how 
trivial/for someone takes (say) iser from 3.2 and backport it to (say) 
3.6.35 in manner that it will be operable with 3.6.35 and unknown 
version of the tools.
