There is a problem with the sd-uhs mode when doing a soft reboot. Switching back from 1.8v to 3.3v messes with the card, which no longer respond (timeout errors). According to the specification, we should perform a card reset (power cycling the card) but this is something we cannot control on this design. Then the only solution to restore the communication with the card is an "unplug-plug" which is not acceptable Until we find a solution, if any, disable the sd-uhs modes on this design. For the people using uhs at the moment, there will a performance drop as a result.
