That one has been in the patch since October for me (see:
http://permalink.gmane.org/gmane.os.freebsd.current/161187 ) on a
i5-3320M. I however could not observe any impact of the error for my
usage beyond the flooded messages. I am not sure if it has to do with
the backlight changes you triggered as I certainly didn't change mine
and still got them.
