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

Status in linux package in Ubuntu:
  Confirmed

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.
