Hi Theodore,

thanks for the hints

well, i have same board with old kernel 3.5.1 perfectly working,
so i can exclude hardware issues.

Same for card issues, same card moved on kernel 3.5.1 board
behave correctly.

Strangely, seems i have "write" issues, if i format the card on PC
and put it back on the soc board, i get no errors on fsck.
If i format on soc board, and fsck from PC i get errors.

I am now moving the discussion to linux-mmc,

Regards,
angelo
