SD slot errors

D. Hugh Redelmeier
I've just installed F28 beta on my Cube Mix Plus tablet.  It seems to
work but a sequence of messages keep showing up in the dmesg
outputnevery 10 seconds.

This looks to me as if it is trying to open the SD card (but there
is no SD card in the slot).

Here's the part of dmesg output where the slot is recognized:

[    2.093265] sdhci: Secure Digital Host Controller Interface driver

Why would it do this?

This should go to the Fedora Test list, not here.
