That suggests that /mnt/newroot isn't being mounted properly...

Something really weird is going on there. Could you please reboot the
machine, perform the following procedure:
1. cat /proc/mounts
2. Run your command to mount /mnt/newroot .
3. cat /proc/mounts
4. Run your command to unmount /mnt/newroot .
5. cat /proc/mounts
and post all the resulting output so I can see what is happening
to /dev/sdb3?
