probe of omap2-nand failed with -16

Hi, I've started working on beagle board. Using pre-compiled kernel (angstrom) - i've got nand driver loaded and running. When I am trying to compile my own kernel from the source, I get error: probe of omap2-nand failed with -16 (EBUSY) I've selected all configs for Nand... Am I missing

Re: probe of omap2-nand failed with -16

-nand failed with -16 (EBUSY) This happens because we moved 'gpmc_cs_request' from nand driver (nand/omap2.c) probe to 'mach-omap2/gpmc-nand.c'. I've selected all configs for Nand... Am I missing something? Mux configuration? GPIO's? Anybody has any idea? Yes. You need to adopt gpmc-nand.c
