Hello,

I've traced the issue to the following lines of code in
sys/dev/mlx4/mlx4_en/mlx4_en_netdev.c in mlx4_en_destroy_netdev():
/* Unregister device - this will close the port if it was up */
if (priv->registered) {
mutex_lock(&mdev->state_lock);
ether_ifdetach(dev);
mutex_unlock(&mdev->state_lock);
}>> mutex_lock(&mdev->state_lock);
mlx4_en_stop_port(dev);
mutex_unlock(&mdev->state_lock);
The issue is that mlx4_en_stop_port() follows the fcall chain below and
tries to fetch the MAC address of the device in mlx4_en_put_qp.
mlx4_en_destroy_netdev->mlx4_en_stop_port->mlx4_en_put_qp
The sequence above causes the kernel to choke because the MAC address
was freed in the previous call to ether_ifdetach in if_detach_internal
with the following call chain:
mlx4_en_destroy_netdev->ether_ifdetach->if_detach->if_detach_internal
I've written a small workaround that works on our test machine, although
I suspect this could potentially cause issues as we're destroying the
port before we destroy the interface. Please see the attached patch for
the workaround.
Cordially,
