Public bug reported:
Network Manager is periocially creating dirty pages that are being
written back to disk and causing uncessary drive wakeups.
Using SystemTap I was able to observe the following dirty pages being
created on the following files
0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011
timestamps
0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011
timestamps.096F6V
0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011
0 795 1 NetworkManager sda1 D Mon Dec 19 13:54:50 2011
timestamps.5RWD6V
..and this occurs regulary every 5 minutes.
Can we either reduce the frequency of these writes or better still only
write the updates when really necessary (e.g. when we close
NetworkManager or the user interacts with NetworkManager which requires
us to really write data back to disk).
