Ok, looking at changes between working -12 and failing -13 kernels, I didn't found anything outstanding so far which could cause a suspend/resume failure.
When the resume fails, do you know if the machine locks up, or is just the screen which remains black? You may try to install openssh, do the suspend/resume, and try login from another machine into the notebook, to see if it's still alive. If pm_trace really doesn't help, and really the machine is dead (locked up), probably just a bisect between the working/failing releases to try to determine what is causing the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/894292 Title: Sandybridge suspend/resume regression on 3.0.0-12-generic/3.0.0-13-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/894292/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
