My Ubuntu AMD64 machine was also seeing hard lockups, with 9800GT video card. Running Ubuntu 12.04 (3.2.0-31-generic). After trying to the latest Nvidia Driver (Driver Version: 304.51), without success I switched video cards (6600GT)
Now no lockups after 3 days but I am seeing the following "NEW" logs in the kern.log. Not sure if this is related but maybe the following logs in kern.log would cause my 9800GT to fall of the bus and cause a hard lock. http://www.cyberciti.biz/faq/debian-ubuntu-rhel-fedora-linux-nvidia-nvrm-gpu-fallen-off-bus/ kern.log ...

No other TTYs can be started. Mouse doesn't move. Keyboard doesn't react. The only solution is hard reset. Seems to happen on a variety of configurations, including nVidia, ATI and Intel graphics. If you are still able to TTY or SSH into other sessions, move the mouse or use the keyboard, file another bug. Thx. Joris V. (brains). Update: 5/21/2012 Updating the kernel to 3.3.6 as suggested by Michael in #91, the system seems stable, no freezes yet in 5-6 hrs of using and watching videos for couple of hrs. Original description: I recently installed newly released ubuntu 12.04 LTS 64 bit version on my desktop. And it is frequently freezing, for the first few hours it ran smoothly and when I started watching videos it started freezing randomly. I have to use hard restart every time. Initially it was only during videos but now even during normal browsing it is freezing. I am using on board graphics and do not have any graphics card installed. Can someone please help me here, I really love the new looks of 12.04 and it bugs me not being able to use :( Below is my hardware configuration: Processor: Intel CORE i3 processor (2nd generation) Board: Intel® Desktop Board DH67BL Ram: 4GB Graphics: On board HDD: 500 GB Please let me know if you need more information, or any specific logs I can capture (and how).
