Are you sure this happens between 2013.05.1 and 2013.06.0? The only changes in the mtd stuff are: ae6f751 nand_base: sync flash detection functions with linux 3.9's code c8af035 Merge branch 'for-next/misc' 7c15fd1 NAND: imx: Fix memory leak d8ee54f mtd: Nand: Use dev_add_param_bool for erasebad parameter 7c6c61f treewide: Use dev_add_param_int_ro where possible 973176d mtd: update NAND manufacturer names from the kernel 4c2bdc8 nand_base: detect more ONFI flash So the only patches which seem to change something are from you ;) Does the 'md' command still work and shows meaningful content in the NAND?
