In this debian bug report they discuss the problem on another kind of level. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689268
For my understanding, the but has to do with the kernel graphics drivers used for Intel Ivy Bridge (perhaps only GPU HD4000?). I think the problem is well known by some kernel developers. But for a solution it seems we need to wait. I was not able to understand the discussion in the debian bugreport in all facets. Maybe someone from the ubuntu kernel team can comment this? ** Bug watch added: Debian Bug tracker #689268 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689268 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently. Status in “linux” package in Ubuntu: Won't Fix Status in “xserver-xorg-video-intel” package in Ubuntu: Won't Fix Status in “linux” source package in Precise: Won't Fix Status in “xserver-xorg-video-intel” source package in Precise: Won't Fix Bug description: Update: 6/12/2012 This bug is about a complete system lock-up. 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).
