    In addition to file system cacheing problems that can be solved via
    "sync", the flash system itself (e.g. a Compact Flash card) might have a
    reset feature (pin or command).

    The rebooting might trigger this reset and thus the Flash system might
    abort the write cycle. This might result in bad data, file system error
    or even in destruction of the internal bad block lists of the Flash
    system and same would become completely unusable.
