It is sandy bridge, but I see no evidence that it's RC6 related. I've had RC6 enabled on this machine since December and only just recently started seeing it. If I disable RC6 now I can reproduce it, and if I go back to earlier kernels (as far back as 3.2.0-3.9 from early December) I can reproduce it with RC6 disabled. So I'm fairly certain this is _not_ related to RC6.
I am getting the idea that this could somehow related to intel graphics though, given my inability to reproduce this on a radeon system. I'm going to explore that a bit more today. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/938770 Title: Desktop becomes completely unresponsive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/938770/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
