Looks like cq use-after-free? I have no idea where.
see if you have in the code base you're using (why not the stock 3.18.14
driver, BTW?) all the synchronize_irq
calls we have in the latest upstream driver:
drivers/net/ethernet/mellanox/mlx4/cq.c:371:
synchronize_irq(priv->eq_table.eq[MLX4_CQ_TO_EQ_VECTOR(cq->vector)].irq);
drivers/net/ethernet/mellanox/mlx4/cq.c:374:
synchronize_irq(priv->eq_table.eq[MLX4_EQ_ASYNC].irq);
drivers/net/ethernet/mellanox/mlx4/eq.c:1088: synchronize_irq(eq->irq);
