["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

rCX, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

** Description changed:

  jbd2 writes blocks to the hard disk every 5 seconds.  This makes an
  annoying click/tick noise and prevents the disk from spinning down to
  conserve power.  jbd2 appears in logs as several entries like...
  
   Jul 19 21:35:45 edge kernel: [ 3312.913759] jbd2/sda5-8(350): WRITE
  block 42280704 on sda5
  
  ... and can be observed using iotop. Since the noise only occurs in
  Ubuntu and not in Windows 7 it is probably a software problem.  The
  excessive writes may reduce the disk's lifespan.
  
- Other info...
- * OS: Ubuntu 10.04 LTS
- * Disk fomat: ext4
- * Kernel: 2.6.32-23-generic-pae
+ WORKAROUND: Adding commit=60 to the partition's entry in fstab increases
+ the interval to 30-45 seconds.
