I am also having an issue where my system completely locks up. Mouse / keyboard are unresponsive and I am unable to ssh in from another system.
This is a new build with all new hardware: ASUS H81I-PLUS Socket 1150 w/ Intel H81 Chipset Intel Pentium G3220 Dual-Core Processor @ 3.0 GHz Team Vulcan 8GB (2 x 4GB) 240-Pin DDR3 1600 (under clocked to 1333 by the BIOS) Intel 330 Series 60GB SSD on-board Intel graphics connected via HDMI to a 24" Samsung LCD TV I was originally running openSuSE 13.3 w/KDE, but as this system is meant to be a multimedia system, it was causing more trouble that I wanted to deal with. I do not recall it freezing at any time. I then installed Kubuntu 13.10 64bit as the multimedia support is better than SuSE. This is when I started to get multiple lock ups. I thought maybe it was due to something not being happy with 13.10, so I installed 12.04.3 LTS w/ KDE 4.12. I also removed the 8GB 'Team' memory and installed a single 4GB ADATA 1333MHz DIMM. This appeared to have resolved the issue, but it locked up on me three times yesterday. Once while using Amarok (remote mySQL database & collection on a FreeNAS NFS share), once while just using the desktop and another while attempting to play an 800MB .MKV file in XBMC standalone (remote mySQL, file located on a FreeNAS NFS share). I've checked the various logs, and there does not appear to be anything of any relevance as nothing 'crashes' exactly, the entire system just locks. I've disabled all power management features & functions. No wi-fi hardware installed / enabled. Cat 6 gigabit network connection.

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).
