Please also note that: - assebet_defconfig currently doesn't even enable ide-cs (CONFIG_BLK_DEV_IDECS) in the mainline kernel - neponset_defconfig doesn't even enable IDE (CONFIG_IDE) in the mainline kernel so there is no risk of breaking anything.. :-) Best regards, -- Bartlomiej Zolnierkiewicz Samsung R&D Institute Poland Samsung Electronics
