Same story for me on a thinkpad x220, sandy bridge, core i5, hd 3000. When using chrome, (but not only : last time it was syslog gui), and even under normal cpu load, the system freezes 2-3 times a day. The sound works, the mouse also, but you can't do nothing (even ctrl-alt-fx) but hard reset.
I got this issue on Debian Wheezy, Ubuntu 13.04, but not xubuntu 13.04. And I've experienced nearly two years of perfectly stable system on Fedora 17 (same gnome version as debian wheezy, 3.4) -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to a duplicate bug report (644740). https://bugs.launchpad.net/bugs/946899 Title: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
