** Description changed: The commit interval for the ext3 filesystem should be higher than 5 seconds for laptop users (at least while on battery) to prevent unnecessary disk-activity when the head is parked or the drive is spun down. ext3 partitions should be mounted with commit=X where X is a number in seconds. /proc/sys/vm/dirty_writeback_centisecs and /proc/sys/vm/dirty_expire_centiseconds should be changed appropriately.
