I think I am having the same issue here with Ivy Bridge. Recently got a
new machine and running Ubuntu 12.10 (Quantal), I was on Wheezy before
with the same issue. Using the standard kernel I was getting system
lock-ups with the screen going corrupted and no input possible at all.
I've followed this thread through trying out various different options
with boot parameters (mtrr) and also have now got the system on the
Liquorix 3.7.x kernel. Same crashes.
It happens when there is user input, I can leave the machine run without
touching it and it will be ok, but when I interact I'll randomly get a
crash. These could be minutes apart, or hours. But right now are inevitable.
I'm fairly technical, but not a kernel hacker, I'm quite comfortable
compiling etc. So if there is anything I can try or add, then please let
me know.
Here are a few system details:
