@unknown.obvious - could you please make the following change, rebuild an upload the resulting uImage: drivers/mmc/host/omap_hsmmc.c change: #define OMAP_MMC_MAX_CLOCK 52000000 to #define OMAP_MMC_MAX_CLOCK 48000000 that seems to me as a possible reason for having -110 error with some sdcards, as in stock n900 kernel the max frequency is 48MHz
