The RDMA CM module might invoke erdma_create_ah() or erdma_destroy_ah() in a non-sleepable context. Both of these functions will call the erdma_post_cmd_wait(), which can potentially sleep and occasionally lead to a hard lockup. Therefore, post the create_ah and destroy_ah commands in polling mode if the RDMA_CREATE_AH_SLEEPABLE and RDMA_DESTROY_AH_SLEEPABLE flags are not set, respectively.
