[Bug 993187] Re: ubuntu 12.04 completely freezes frequently.
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.
