For information, I cannot reproduce your issue (it does not mean that the issue does not exist). In add, if you obtain undefined references, it should only happen when CONFIG_MMC is not defined. Can you check that your Modules.symvers is up-to-date (by running a 'make modules') ? -- Jérôme Pouiller
