Up Squared on Linux - getting mmc error messages

I have an 8GB, 128GB N4200 Up Squared. I installed Fedora, with the 4.11 kernel. I have been getting a lot of timeout errors on the mmc. Here is an example:

[Sun Jun 11 21:26:31 2017] mmc0: Timeout waiting for hardware interrupt.

Any ideas what is going on? Things hang for a few seconds when this happens. Thanks.
