Have you tried switching to a VT and back when this happens? There was a
bug in... I *think* it was something like opengl ... recently, whereby a
bunch of unrelated programs (chrome/chromium included) could freeze the
display. Switching away from X and back caused the display to refresh
and things would work again (for a time).

This is less's representation of null characters and is an artefact of
journaling file systems. Syslog has told the file system "I'm about to
write X bytes to /var/log/daemon.log" and then, at some point during the
writing of that, you've killed the power. During either fsck or mount
(depending on the file system), the journal is replayed - that is, there
is a log saying "X bytes were being writen to /var/log/daemon.log". Now,
most of those bytes never made it to the disk, but the record is still
there. So the file grows by X bytes of nothing. Now the file system is
consistent (the metadate, at least, the idea being that it's better to
have SOME of the file still there, rather than a broken filesystem)
