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

StewartM, 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

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.

Title:
  Apparent Encryptfs Crash When Removing a USB Drive

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This has been happening sporadically whenever I remove a USB drive.
  Most of the time, the removal goes smoothly. However, occasionally
  (like today) I get a black screen filled with error messages. I can
  get back the GNOME desktop by Pressing ALT+F2 (which gives me the "Run
  Application" command).

  Looking at the error today, it seemed to involve the kernel. I then
  went to /var/log/ and looked at kern.log and sure enough, there was
  the same error text that I saw on the screen. I've snipped out the
  part of the code that I saw:

  I don't know if this is a security bug; if it is an encrypt-fs crash I
  would classify it as such. I am attaching all of  the \var\log\kern.og
  file.
