What does it show in messages after the mount? That is where I would expect the underlying read errors to be. I have also had some issues with certain sdxc readers seeming to not work well with some cards. There are also a significant number of MMC changes going into the kernel recently. There is an entire new set of code (not sure if has made it into the latest released kernel yet) for the UHS-II cards (All UHS-II cards are working backwards compat for UHS-I). You might try a different machine/reader and see if it works on a different one. The issues I saw only happened with the larger and/or faster cards and only in some readers.
