I can reproduce the problem every single time, so it might have something to do with the resolution or dependent things like the used graphic memory or the bandwidth... Do you have the amd64 version of ubuntu or the i386? If your system did boot up correctly, do you get the problem during the normal, daily usage or does it just occur during the boot process? Does the problem start right after the grub-menu or during the switch to the lightdm greeter?
For me, it's amd64 and the lockup always is during transition to the lightdm greeter. I've changed the status to confirmed due to two people being affected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1174042 Title: System crashes with open-source radeon driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1174042/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
