I installed 12.04 in September. In the last few weeks my computer has been freezing on a daily basis. I lose mouse, keyboard, can't cntr-alt-F1 - have to hard stop.
Some google searches showed that many others are experiencing this. Some say its a video driver problem, others say it's not - others say a kernel upgrade (to 3.3.6) is necessary, others say that doesn't fix the problem.
I came to the Ubuntu forum to look for more info - but could not find anything...

Please point me to where i can get more info and a possible solution for this problem.

I am using ubuntu 12.04 on 64 bit Dell inspiron laptop.
Intel® Core™ i7-3612QM CPU @ 2.10GHz × 8
Ivy Bridge Graphics Controller
driver=i915 latency=0
3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09

Thanks,
