Hi all, I wrote a mtd-nand driver and enabled it with YAFFS(CVS Nov9) on 2.6.18. When I mount the mtd partition of a large page nand chip, everything works fine. But When I replace the large page nand chip with a small page nand chip,everything works ok except mount costs about 8 seconds. It's too long, I think. The same kernel and driver, the same hardware just except the nand part number( NAND01G and NAND128W), any clue? Did anyone encounter this issue? Welcome any suggestions! Thanks, -Aubrey
