Did reboot & was presented with several messages : general protection fault: 0000 [#31] SMP Status in linux package in Ubuntu: Incomplete Bug description: I noticed a problem last week where my GUI locked up while I was trying to unlock it. At the time I was unable to get the system to generate a report or find anything obvious to me in the logs, though I am no expert. I did manage to enable some more analysis tools for next time and it seems that next time has just occurred. 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. Thinking it might just be the GUI locked up, as it seemed to be last week, I tried to ssh in from another machine. tt@172.16.20.39's password: Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.16.0-37-generic x86_64) * Documentation: https://help.ubuntu.com/ Last login: Fri May 1 12:46:41 2015 from 172.16.20.98 tt@tt-ul-dt:~$ tt@tt-ul-dt:~$ tt@tt-ul-dt:~$ top Segmentation fault tt@tt-ul-dt:~$ ps As you can see, 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 thinking that might be a simpler program and able to show me something. That seemed to lock up the ssh session. Next I did a quick Google to see what I might be able to do remotely to help debug things. Nothing helpful presented itself to me so I did Ctrl + Alt + F4 to try and get access via one of the other virtual terminal things. I was able to enter my username and password 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. After that I figured a clean shutdown was about the best I could do. I found http://askubuntu.com/questions/53263/shut-down-computer-from- keyboard and started the Alt + SysRq + r, e, i, s, u, o. The first two of three keys reported that they were disabled but after that it seemed to work. After the shutdown, I left the machine till 09:01 and powered it on again. It booted, I logged in and was then presented with several "System program problem detected" messages. I am now trying to work through them in the sequence they were presented. $ lsb_release -rd Description: Ubuntu 14.04.2 LTS Release: 14.04 ProblemType: KernelOops DistroRelease: Ubuntu 14.04 Package: linux-image-3.16.0-37-generic 3.16.0-37.49~14.04.1 ProcVersionSignature: Ubuntu 3.16.0-37.49~14.04.1-generic 3.16.7-ckt9 Uname: Linux 3.16.0-37-generic x86_64 Annotation: Your system might become unstable now and might need to be restarted.
