[Bug 993187] Re: ubuntu 12.04 completely freezes frequently.
Hi,
I also had the problem where my kubuntu 12.04 install was completely
hardware freezing - i.e absolutely no response from any input device and
in particular CTRL+ALT+SysRq REISUB was not responding at all either.
I found the problem was happening close to when I was switching the
external monitor on & off (I switch it via a KVM switch).
Note that I use x11vnc to remotely connect to the same desktop, and I
think that may have helped trigger the fault.
I updated ALL installed software, but to no avail, it was happening 3 or
4 times a day ...
*** THE FOLLOWING FIX WORKED FOR ME -been ROCK SOLID for a week now ***
I installed the following kernel upgrade described here:
http://askubuntu.com/questions/142192/can-i-install-linux-kernel-3-4-in-
ubuntu-and-kubuntu-12-04
So I downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/
And did:
sudo dpkg -i linux-headers-3.4.0-030400_3.4.0-030400.201205210521_all.deb
sudo dpkg -i linux-headers-3.4.0-030400-generic_3.4.0-030400.201205210521_i386.deb
sudo dpkg -i linux-image-3.4.0-030400-generic_3.4.0-030400.201205210521_i386.deb
Rebooted, and the problem completely disappeared (so far anyway !)
My machine specs:
uname -r
3.4.0-030400-generic
MOBO: ASUS P8Z77-V-LX
I am using the onboard video, with nothing but the default kubuntu video
installation.

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).
Thanks,
Ketan Patil
