I'd just like to mention this isn't just specific to i3, i5, i7 Ivy/Sandybridge etc. I'm seeing this on a 3Ghz Pentium 4 system + nVidia.
Kernel 3.3.5 and 3.3.6 improved the problem no end but still getting hard freezes as per my comment #27 with Unity 3D. NO freezing at all Unity 2D! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
