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 Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
