With standard settings, system doesn't boot. It stops booting somewhere around framebuffer initialization.
When booting with nomodeset the system boots but X cannot initialize the radeon driver and starts with VESA driver. I have two graphics cards: Radeon HD 3300 Radeon HD 4650 Booting with 3.5.0.26 works fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1158562 Title: system will not start after updating to kernel 3.5.0-27 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-quantal/+bug/1158562/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
