BugLink: https://bugs.launchpad.net/ubuntu/+bug/254837 Spurious shared interrupts or early probing interrupts can cause the hostap interrupt handler to oops before the driver has fully configured the IO base port addresses. In some cases the oops can be because the hardware shares an interrupt line, on other cases it is due to a race condition between probing for the hardware and configuring the IO base port. The latter occurs because the probing is required to determin the hardware port address which is only determined when the probe can interrupt the hardware (catch 22). This patch catches this pre-configured condition to avoid the oops.
