[Bug 1453029] Re: Tried to login, GUI locked up. Did reboot & was presented with several messages : general protection fault: 0000 [#31] SMP


Thomas A. F. Thorne, could you please test the latest upstream kernel
available from the very top line at the top of the page (the release
names are irrelevant for testing, and please do not test the daily
folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will
allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. 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 by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:

Please note, an error to install the kernel does not fit the criteria of

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.

Bug description:
  Today I tried to login to the system. The screen progressed passed the
  password entry but failed to display the desktop background, the side
  bar or the top bar. I left it for a few minutes while I got a coffee
  but it was still in the same state when I returned. I managed to SSH
  in but failed to do much else. When I tried to take a look at what was
  going on with top I got a message about a Segmentation fault. I then
  tried ps and the ssh session locked up.

  I was able to enter my username and password at a vt but as soon as I
  had done so I seemed to get some sort of log trace on the screen. It
  mentioned the USB mouse I had being connected. I was not able to enter
  any commands so instead I tried unplugging and reconnecting the USB
  memory stick I had. I could see it registering in the trace. I did the
  same with a USB temperature probe and could see it connect too.
