Good to see you're identified a specific issue.

Any of the above.

Something else to consider is caching. If your NAND accesses are being cached 
then that will play merry hell with the signals that get to the NAND chips.

Driver and hardware timing are intertwined and it is often not realistic to 
say that the hardware is good but the driver is faulty, or vice versa.

I once fixed a lubrication problem in software... but that's a story for 
another day!
