Well, in the meantime I did create a new bug report for the freezes with xserver-xorg-video-intel-lts-quantal and Intel Sandy Bridge on Ubuntu 12.04: #1161088
I did re-use this bug as those Sandy Bridge i915 drm hangs & system freezes do feel pretty similar to this bug and there was just about the same bug on Ubuntu 11.10... -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
