powertop reports many things but not really what I'm looking for (since disk access is not the only power consuming work), but I can find more about pdflush there: 0,3% ( 0,4) pdflush : do_journal_end (delayed_work_timer_fn) Sure this is not the worse process, but this may be sufficient to prevent the hard disk from sleeping and cost more power than it appears to. So is that just a matter of filesystem journal write? I'm using reiserfs3 on my home and root partitions.
