My embedded fs are 
ppcboot+kernel+ramdisk(rootfs),However
ramdisk will take 4.5M ram.

I am going to switch to jffs2,
but could you tell me the function of
your 1M ramdisk?
Would you please check
http://lists.infradead.org/pipermail/linux-mtd/2003-January/006836.html
and I state my situation there.

Thank you!
