At least LID reassignment can trigger a race condition in the SRP initiator driver, namely the receive completion handler trying to post a request on a QP during or after QP destruction and before the CQ's have been destroyed. Avoid this race by modifying a QP into the error state and by waiting until all receive completions have been processed before destroying a QP.
