The MMC layer uses the standard work queue for doing card detection. As this queue is shared with other crucial subsystems, the effects of a long (and perhaps buggy) detection can cause the system to be unusable. E.g. the keyboard stops working while the detection routine is running. The solution is to add a specific mmc work queue to run the detection code in. This is similar to how other subsystems handle detection (a full kernel thread is the most common theme).
