Timo,
this affects me too, I have:
Intel(R) Core(TM) i7-3517UE CPU and HM75 chipset, Ubuntu 12.04 64-bit.
On my system with kernek 3.2.0-24 freeze can be reproduces in 2-3
minutes under high load cpu and 3D operations:
#!/bin/bash
cpu_num=`cat /proc/cpuinfo | grep processor | wc -l`
for i in `seq 1 $cpu_num`; do
gzip -c /dev/urandom > /dev/null &
vblank_mode=0 glxgears &
done
top
3.4.0 seems to be stable couple of days, is it possible to backport
whole 3.4.0 kernel to 12.04?
