Quite a few people have the problem that they use automatic file system checks and may have a check at a bad point in time.
For example if they boot their notebook before a presentation or the battery is low.
e2fsck the tool which does the file system check has a config file (it doesn't exist by default) with an option to workaround this.
Just insert:
[options]
allow_cancellation = 1
to /etc/e2fsck.conf and you will be able to press Ctrl-C during the file system check to cancel it.
