With the race condition, the "ha->mbx_intr_comp" will get an extra complete() call. The extra complete call create erroneous mailbox timeout condition when the next mailbox is sent where the mailbox call does not wait for interrupt to arrive. Instead, it advance without waiting. Add lock protection around the check for mailbox completion.
