Previously I was using Doug's rdma rxe branch + sagi's rxe fixes + rebased on nvmf-all.2. To simplify, I have now gone to just straight nvmf-all.2. Also, I separated the host and target to different nodes and reproduced the problem. It?s the host side that is crashing. Same GPF with RIP:
RIP: 0010:[<ffffffff810d04c3>] [<ffffffff810d04c3>] get_next_timer_interrupt+0x183/0x210
