Yes, I believe we're using the same hardware.

With the patch it still fails.

During boot devices were:
* mmcblk0 internal 64GB SSD (detected).
* mmcblk1 internal card reader with 64GB bootable card in it (fails to
be detected).
* External USB reader that has 2 slots, one is empty, the other has a
1GB microsd (detected).

Looks like the same problem where the card won't respond and times out.

I still need to see if I can get some debugging information from a
Linux kernel because everything works fine there. I'm not sure how to
go about turning it on.
