You shouldn't pad the image up to the size of the device (or partition, if 
you were using partitions) or you will get this error, if there are bad 
blocks in your flash (there usually are). However, your subsequent test 
mount seems to work, so you seem to have gotten all valid data into the 
flash anyway, so it still doesn't explain why it doesn't want to be 
mounted when 
the kernel boots.
