There's another issue with aci.lock and previous patch uncovers it. aci.lock is being destroyed during removing ixgbe while some of the ixgbe closing routines are still ongoing. These routines use Admin Command Interface which require taking aci.lock which has been already destroyed what leads to call trace.
