Try enabling CONFIG_MMC_UNSAFE_RESUME:
config MMC_UNSAFE_RESUME
bool "Assume MMC/SD cards are non-removable (DANGEROUS)"
help
If you say Y here, the MMC layer will assume that all cards
stayed in their respective slots during the suspend. The
normal behaviour is to remove them at suspend and
redetecting them at resume. Breaking this assumption will
in most cases result in data corruption.
This option is usually just for embedded systems which use
a MMC/SD card for rootfs. Most people should say N here.
This option sets a default which can be overridden by the
module parameter "removable=0" or "removable=1".
