In the "recent" kernel versions this can at least with the eata-dma driver not happen, since it uses the per-device queues to make sure that every connected device can always have enough commands in the queue to ensure that it can operate without having to wait for the queue to free up.
Before the per-device queues, the sd driver tended to starve all other device drivers by continously flooding the queue.
