Hi Kevin

Is it always the same block/offset? If so then Richard is right, the PEB 
probably got bad.
Is this first boot up after flashing the image? I encountered similar 
behavior on first boot up after flashing the image. What helped me is to 
generate the image with -F flag, or use a UBI-aware flasher (ubiformat 
for example) to flash it.


Thanks,
