I don't have this hardware, so I cannot say much.

Does the dump of the corrupted data make sense?
IOW are only a few bits flipped or is it completely

Han, have you ever tested this driver with UBI?
As I said UBI uses vmalloc'ed buffers. Maybe the driver
is "UBI unfriendly" and needs tamed.

Thanks,
