The attached patch add two extra reads to chip_ready in accordance with the chip data sheet (page 3, "Write Operation Status Detection"). This seems to make the write cycle completion detection reliable. I have not tested the patch on any other chips but I would think that it would be harmless on chips that do not need the extra reads.

1. The patch is not applicable to mtd-2.6.git.
2. Please, add Siged-off-by line.
Look here please:
