I suspect laptop-mode-tools is the culprit: http://sources.debian.net/src/laptop-mode-tools/1.64-1/usr/share/laptop-mode-tools/modules/laptop-mode?hl=418#L418 set_sysctl /proc/sys/vm/dirty_writeback_centisecs "$U_AGE" and usr/share/laptop-mode-tools/modules/laptop-mode: U_AGE=$((100*$DEF_UPDATE)) usr/sbin/laptop_mode:DEF_UPDATE=5 → there you have your 500 -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
