OK, this morning I did some reading over your previous postings to open-iscsi and stgt and also some testing. The news is that I have this reproduced on my setup. When I use a different target, it doesn't happen! so I think we're quite narrowed this to be stgt's fault, we'll see...

Is it correct that at some point you said that a patch of Pete which deferrers sending the scsi response till the rdma-write is completed makes the problem disappear? do you have this patch in a form that applies on tgt's head?

Also, just to make sure we're on the same page: for write you use opat=1 and for read ipat=1 mismatch=1, correct?
