Steps to reproduce: 1. set the LPSS as acpi mode in the bios. 2. boot the system with the kernel parameter: "byt-board.disable=1" 3. on the board run: dmesg | grep mmc 44953 1 dvhart 2014-08-04 17:42:55 +0000 The MMC driver has been updated for Baytrail in recent builds. This problem should now be resolved. I can't test myself as do not have a BakersPort board, but it does work correctly in ACPI mode on the MinnowBoard-Max (E3825).
