you might be right !! but I just compiled the kernel with make allyesconfig & make allmodconfig and then manually set all Filesystem related options to yes !! I think there are Ys in where in Y is a option and m in place wherein m is a option . i checked the .config file .. do you have any comments on this !! - this might be wrong !
Can you please paste you .config ,so that we can have a look at it?? Also please let us know your HDD type and rootfs you are choosing for the root partition? Thanks
