Public bug reported:
System completely froze (no response to input devices, or ssh) and
required a hard reboot.
At the moment of the freeze I had opened up a new tab in the stable
version of Chrome (v20) and was starting to type text into the omnibox
for a search.
I was previously affected by an Ivy Bridge graphics bug that also
resulted in a full system freeze, but the trigger for that freeze (GPU
related work) seems to have been fixed with the recent release of Kernel
3.2.0-27
