"/boot was not cleanly unmounted, check forced" - all the time

Binary package hint: mountall

It happened to me to turn my computer off using the power button. Now *EVERY* time I boot my computer I see the following (I disabled 'splash quiet' options):

/boot was not cleanly unmounted, check forced
  //then it checks /boot for errors and:
mountall: fsck /boot [550] terminated with status 1
