My initial test was only about the mount time. I have now also tried
to exercise the patched file system and with very little testing I get
CRC or ECC errors.
# mount /dev/mtdblock2 /mnt -t jffs2
# mkdir /mnt/testdir
# umount /mnt
jffs2_flush_wbuf(): Write failed with -5
# mount /dev/mtdblock2 /mnt -t jffs2
mtd->read(0x1fbec bytes from 0x1fc0414) returned ECC error
Empty flash at 0x01fc2f1c ends at 0x01fc3000

With plain 2.6.9-rc4-omap1 with fresh CVS MTD code, I don't see anything
weird occuring.
