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

Deepak Sarda, 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 kernel 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-v3.12-rc2

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

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.

  This is with the latest stable lucid kernel (2.6.32-22-generic
  #36-Ubuntu).

  I've also tried a mainline kernel (2.6.35-020635rc1) & still get the
  same errors except that there's an additional stack trace:

  --------------------------------------------------------------------

  I've tried booting with "libata.force=noncq" on both kernels (lucid
  stable & 2.6.35 mainline) but makes no difference.

  I didn't see these errors in Jaunty. I think they started sometime in
  Karmic. I upgraded to Lucid in the hopes that the newer release fixed
  it but no difference.

  I think I've ruled out HDD failure. I get these errors on 2 old (3+
  years) Seagate 7200.10 disks as well as a brand new Seagate 7200.12
  disk.

  There are similar bug reports in launchpad but one difference that I
  noticed is that I consistently see the message "failed command: WRITE
  DMA EXT" while the other reports fail during a read or some other
  command.

  I can very reliably reproduce the errors by running a rdiff-backup
  'restore' operation from an external USB HDD.

  == Steps to reproduce ==
  1. Boot into Gnome & login
  2. Run 'tail -f /var/log/kern.log' in one terminal window
  3. Run 'rdiff-backup --force -r now /media/freeagent/share /share/' in another terminal

  Within a few seconds, I can see the errors show up in the kernel logs.

  Running a fast torrent download will do the trick too.

  Since I can reproduce the problem so easily, I'll be very willing to
  try any special kernel builds to help solve this one.
