I've also been having daily crashes with no logs, complete freeze, no response to magic keys-REISUB Im running Ubuntu 12.04 and I have tried the LTS Enablement stack with no success, currently im at kernel version 3.5.0-25
Ive tried various other tricks on this message trail, but no success so far. I definitely want to get this solved! It seems anytime Im running Unity GUI, I have these problems. Overlapping this fact, is that I usually have VirtualBox running also. (When I run w/o gui, I get uptimes on the order of days) But I have similar Ubuntu setups on other machines that doesnt crash with GUI+VirtualBox running. I do see however a difference in my /var/log/kern.log: Unstable system: kernel: [ 0.004000] Fast TSC calibration using PIT kernel: [ 0.186351] TSC synchronization [CPU#0 -> CPU#1]: kernel: [ 0.186354] Measured 486003664 cycles TSC warp between CPUs, turning off TSC clock. kernel: [ 0.012000] Marking TSC unstable due to check_tsc_sync_source failed kernel: [ 2.962271] vboxdrv: TSC mode is 'asynchronous', kernel timer mode is 'normal'.

Ive had the TSC unstable for as long as I can remember from using this system (Intel DX79TO, i7-3930k) Im going to see if fixing this error will solve my crashing problem. However, I do not see much online on how to solve the unstable TSC. Does anyone else have unstable TSC? -- 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).
