I monitor HDD activity with iotop (in <a>ccumulated mode), and absolutely no process has any throughput but kjournald adds a 30 to 60kB every few seconds, making the hard-disk spin up for no reason. I've even increased "commit" to at least 60 on all my ext3 file systems, but it still happens. It's very annoying. Could anyone help me make it stop?

PS: As if this wasn't bad enough on it's own, every time this happens I get a micro-freeze for a split second!

Any help? So far I've noticed that kjournald writes 3.5 Megabytes for every 500 Kilobytes written by all other processes together. Is that reasonable?
