Thanks for reporting!

I don't fine anything obvious from the mmc host driver point of view.
However, there are a few changes in the mmc core layer which we
already have fixes for.

You may either try my fixes branch from my mmc tree or use Stephen's
tree and the branch pending fixes, to see if that fixes the problem.

git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git fixes

git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git pending-fixes

Kind regards
Uffe
