Title:
  NetworkManager periodically writes to the disk causing wakeups

Status in “network-manager” package in Ubuntu:
  Triaged

Bug description:
  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

  ..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).
