I can confirm that this is still a bug on 6.4.7 (close to current).

Mine fails with Lexar UHS-II cards.  The 2 cards work fine on slow usb sd card readers.   Older SD cards do work on both of these readers.  The issue seems to be the newer cards that have this issue.

Errors are this:
160866.008169] mmc0: cannot verify signal voltage switch
[160866.441037] mmc0: error -110 whilst initialising SD card


I have at least 2 different machines that have these cards in them, and this behavior is on both.

I can collect for this issue.
