This message comes either, if you try to erase a bad block, which is not
likely, as all your blocks would be bad or the erasefunction is not
successful
Do you use the latest CVS code ?
If yes, there were a lot of changes in NAND the last few days.
Can you switch on the debugging in MTD and provide more detailed information.
Please do a
echo 9 >/proc/sys/kernel/printk
before you start the erase .
