FWIW: I have a ThinkPad T430s with the i7-3520M. Running the stock 12.04 linux-image-3.2.0-26 kernel i was seeing periodic lockups as described in this issue. Running 2-4 concurrent instances of "vblank_mode=0 glxgears" was enough to cause an immediate lockup.
I installed "linux-image-3.2.0-27-generic" (3.2.0-27.44~pre201207100400) from "ppa:kernel-ppa/pre-proposed" and am currently watching 10 instances of glxgears that have been happily chuging away side by side for the past 20 minutes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999910 Title: [IVB]12.04 64 bit System freezes (mouse, keyboard) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/999910/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
