Re: [PATCH 1/1] mmc: Some microSD cards are not recognized by PCIxx12SDA controller

[Josà MarÃÂa FernÃndez GonzÃlez]

It is curious. I have concentrated my tests on 2.6.29 with HZ=100 and no preemption, and I have done next tests with my microSD card and laptop:

*	mmc_delay(2) -> FAIL
*	mdelay(2) -> FAIL
*	mmc_delay(10) -> Works!
*	mdelay(10) -> Works!

And by mistake I found that:

*	msleep(2) -> Works!

	Best Regards,
