mount costs too long

[Aubrey]

Hi all,

I wrote a mtd-nand driver and enabled it with YAFFS 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 except the nand part
number( NAND01G and NAND128W), any clue?

Did anyone encounter this issue? Welcome any suggestions!

Thanks,
