This bug is not fixed oneiric. I am running Xubuntu 11.10 and still experiencing these random freezes on my T420. Subjectively seems like certain graphics-heavy applications/plugins make it happen more often. Also subjectively seems like some of the kernel options and phoronix drivers make it happen less often.
Today, for example, I had two freezes occur within 15 minutes of each other when using the new Google+ hangouts interface (on Firefox). I was able to SSH into the system, but had to reboot in order to get the display and input devices to work properly. If there is anything I can share (logs, configuration) that will help, please let me know. Also, if grabbing an early Precise build would help, I'd also give that a try... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/792849 Title: Lenovo ThinkPad T420 random hardlocks with Sandy Bridge graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/792849/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
