Hi Tony, This patch changes the sequence of how the host drivers set_ios function gets called during probe. Before: 1. mmc_power_off 2. mmc_power_up Now: 1. mmc_power_up My guess is then; the omap driver set_ios function requires that mmc_power_off is called before a mmc_power_up. Hopefully this requirement can be removed and fixed in the host driver somehow. Please get back to me if you need some more assistance around this matter.
