At the same time it sees SDHCI just fine. How about setting CONFIG_MMC_RICOH_MMC? config MMC_RICOH_MMC bool "Ricoh MMC Controller Disabler (EXPERIMENTAL)" depends on MMC_SDHCI_PCI help This adds a pci quirk to disable Ricoh MMC Controller. This proprietary controller is unnecessary because the SDHCI driver supports MMC cards on the SD controller, but if it is not disabled, it will steal the MMC cards away - rendering them useless. It is safe to select this even if you don't have a Ricoh based card reader. -- Chris Ball One Laptop Per Child -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
