I forgot to add that on resuming, when I access /mnt partition , I get
the "FAT-fs" errors as described above. Then I umount and mount the
mmc device, I am able to access the mounted device.
But my question still remains as why the mounted partition of mmc is
in-accessible on resume and why does it become accessible when I
unmount and remount the mmc.
