I saw it happened from below ipoib debug output on testing ehca2:
static void ipoib_cm_start_rx_drain(struct ipoib_dev_priv *priv)
{
....
/*
* QPs on flush list are error state. This way, a "flush
* error" WC will be immediately generated for each WR we post.
*/
p = list_entry(priv->cm.rx_flush_list.next, typeof(*p), list);
if (ib_post_send(p->qp, &ipoib_cm_rx_drain_wr, &bad_wr))
ipoib_warn(priv, "failed to post drain wr\n");
...
}
Thanks
