Prevent this to happen again even if you want to log this, 

set in /etc/init.d/klogd

KLOGD="-k /boot/System.map-$(uname -r) -c 3"

I wonder why this script does not create /etc/default/klogd like other
init script.  Although it is conffile, I do not like editing it
directly for this trivial configuration.
