Hi all!

I noticed that on Hardy, when (and only when) my laptop is on battery,
the hard disk makes a sound every second or so, and never stops, even
when no application is running but the desktop.

atop reports this is pdflush that is writing something to the disk, but
I could not identify why. What is strange is that as soon as I plug the
power cable, the sound stop (rather illogical, sin't it?). Before
reporting a bug I'd like to know if anyone sees this behavior - just
unplug the cable and listen!
