This added long timeout at boot time. To alleviate the problem, the default timeout is reduced to one second during the setup phase. [1] - Some configurations crash at boot if rtsx(4) is defined in the kernel config. At boot time, without a card inserted, the driver found that a card is present and just after that a "spontaneous" interrupt is generated showing that no card is present. To solve this problem, DELAY(9) is set to one quarter of a second before checking card presence during driver attach. - As advised by adrian, taskqueue and DMA are set up sooner during the driver attach. A heuristic to try to detect configuration needing inversion was added.
