OK, this is a pretty serious bug in mlx4_ib if true. Are you sure that you really are seeing some pending work requests not generating a flush error when the QP transitions to the error state? Keep in mind that transitioning the QP to the reset state can cause completion entries to disappear after they are generated. - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
