Chris Clayton writes via Kernel.org Bugzilla: Sorry, I can't help to debug that because the card reader works fine on my NUC6CAYH. All I can say is that error 110 is a timeout. It's interesting that at comment 17 above, Yannis reported that the patch worked on the same hardware platform. However, that was on an Ubuntu 5.4.x kernel. I'd be tempted to raise this issue on with the Fedora support people.
