This bug no longer reproduces. I still have ubuntu 12.04 LTS and the same machine, but I reinstalled it a few months after I submitted this bug.

I have Ubuntu 12.04 LTS and it freezes all of a sudden. The keyboard/mouse stop working. Can't open any other TTY. The only solution is a hard reboot from button. Configuration: Description: Ubuntu 12.04.2 LTS Release: 12.04 Lenovo ThinkPad Edge Laptop Intel® Core™ i5-3210M CPU @ 2.50GHz × 2 OS-type: 32-bit 4GB RAM VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) VGA compatible controller: NVIDIA Corporation Device 0de9 (rev a1) I have installed on it a basic LAMP configuration, plus netbeans 7.2, FileZilla 3.5.3, Google Chrome. I also have an external monitor (I mention it because there was another bug similar that was saying that the monitor is the problem, but mine freezes regardless if I use or not the monitor) I don't think there are any logs as the system freezes without any warning (no CPU overheating, no lag...) It doesn't matter how many programs I have opened, because it freezes even if I close all programs, or even if I have Netbeans, Chrome(10+ tabs +youtube), FileZilla, messenger, libre office, remmina and music on all in the same time. Sometimes it crashes as soon as I start using a program, other times crashes 2,3 times one after another on restart, and other times it doesn't crash for days (the longest period without a crash is for 3-4 days). What is even more strange is that I have another laptop with Ubuntu ( a Dell Inspiron), with same software configuration and external monitor, and it never crashed. The only software difference is that the one that doesn't crash I downloaded the OS from ubuntu.com, and for the one that crashes I took the OS from a Romanian proxy. Could these be the issue? Please tell what log files to upload that may be of any help.
