I had this bug on my HP dm1 4xxx series notebook (AMD e-450 / radeon 6230m / BCM 4313). I had full system lockup with no other option but hard reset. It occurs in other linux distributions also but Ubuntu suffered the most by a long shot. I followed all the threads and tried many of the suggestions. Over two weeks I have tried 3.2, 3.4 and 3.5 kernel and had many many reinstalls. I have tried with/without proprietary amd catalyst drivers (as well as different versions) and with/without the proprietary broadcom drivers. I also tried various desktop environments. The problem persisted despite my efforts. Most often, the computer would crash at high system loads, when the fan was just kicking in and the computer was hot. However I believe I now have a workaround (working for 3 days without problem): Disable the kernel thermal module with "thermal.off=1" 1. sudo gedit /etc/default/grub from: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash thermal.off=1" 2. sudo update-grub I found several sources for this workaround including: arch forums, ubuntu forums and the hpsupport forums. If you disable the OS's control of the fan with this workaround then I would be careful that the BIOS is doing it's job correctly without the OS by paying attention to the heat of your laptop and by listening to the sound of the fans. Also, ensure that any useful fan control options are enabled in BIOS settings. -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.

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).
