Happening for me too after recent updates. GPU hangs would happen up to multiple times per minute. Originally I was running precise and using the precise kernel/X11 stack. I reinstalled from 12.04.2 media with the quantal kernel/X11 stack, but after getting the latest updates it started happening again.
I've now installed the proposed 3.5.0-28 kernel and it seems to have fixed the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1140716 Title: [regression] 3.5.0-26-generic and 3.2.0-39-generic GPU hangs on Sandybridge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1140716/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
