If this is case, it should be possible to reproduce with:

cp a bunch of stuff to /ext4
unmount /ext4
mount ext4
compare data

If you're not getting a clean unmount of the test FS during the reboot,
its a different test.  Trying to reproduce here, so far its clean.
Could you please double check for failed unmounts?

Thanks,
Chris
