This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1169300

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0]. You will need to install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

When running apport-collect as instructed from the automated email:
UnicodeEncodeError: 'ascii' codec can't encode character u'\xff' in position 52424: ordinal not in range(128)

attached is the full log from apport-collect

Joseph, I can test the 3.9 kernel and will report back. This issue does not occur frequently (twice in two months). So I am not sure when that well be.

[Aisthesis (aisthesis)]

I'm now on Linux slim 3.9.0-030900rc6-generic #201304080035 SMP Mon Apr 8 04:36:25 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

It looks like rc7 is the latest but did not build all the way. Anyway, fingers crossed.

[Aisthesis (aisthesis)]

I have been on google looking into this issue (which I did not have the time for at work earlier).

I found this error has been reported dating back to 2009. I also found that this is not isolated to the Ubuntu kernel as I found reports on Fedora as well. So the problem is across distributions and has existed for some time.

I found that the majority of other users from the brief reading I did only experienced disconnected wifi. However in my case, this issue resulted in data loss due to the hard lock I experienced. Namely my Intellij configuration for different environments on more than one project and some unsaved work I was in the middle of.

[penalvch (penalvch)]

aisthesis, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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-rc3

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.
