You have with laptop_mode the same problem than with noflushd (you're losing 29 minutes of data if your laptop crashes and the laptop_mode timeout is 30 minutes). Where the laptop_mode shines is in its mechanism to group write access every time the HD has to spin up (for a read for instance) --

AFAIK, on ext3, the commit interval can't be changed. So, every time a process write sth on disk, the journal commit occurs physically within something like 10s. Moreover, without noflushd, the kernel buffers are flushed every 30s (or less, I can't remember) Try mounting you partition using ex

2004-04-02 Thread Jeff Coppock
Lately, I've been working on making my laptop as efficient on power as possible. Dell Latitude C610, BIOS version A16, Testing release. There is a lot of information out there on this subject and I've accomplished quite a bit on the system: 1. I mount my EXT3 partitions with noatime 2. I hav
