[Bug 607560] Re: jbd2 writing block every 5 - 10 seconds, preventing disk spin-down and making noise

[Matthew Holtz]

rCX, I'm not sure I'd call every 1-2 minutes tolerable, though it is
certainly better.  Why does there need to be any excess disk activity at
all?  On a netbook install, 1-2 minutes will still prevent the system
from going to sleep automatically because the disk activity fools the
system into thinking it's not idle.  Besides, its loud.

Is there a mechanism to disable this process or is it required if
journaling is used?  Why doesn't ext3 have this behavior?  It's also a
journaling filesystem, right?
