Was there a precise kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced.
You report you can install Oneiric, so maybe you can boot some Precise kernels on Oneiric to try and find what version introduced the regression. ** Tags added: regression-release -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/969276 Title: 12.04 64bit beta-2 doesnt boot on Lenovo W520 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/969276/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
