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 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-27-generic 3.2.0-27.43 ProcVersionSignature: Ubuntu 3.2.0-27.43-generic 3.2.21 Uname: Linux 3.2.0-27-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
